I built support for function calling into SK!
Related to/fixes:
- #2315
- #2175
- #1450
### Description
<!-- Describe your changes, the overall approach, the underlying design.
These notes will help understanding how your code works. Thanks! -->
This implementation builds on top of all the existing pieces, but did
require some major work, so feel free to comment on where that is or is
not appropriate.
- Added a `ChatMessage` class to capture the relevant pieces of function
calling (name and content)
- Added a `complete_chat_with_functions_async` into
OpenAIChatCompletions class
- Added a `function_call` field to ChatRequestSettings class
- Added several helper functions and smaller changes
- Added a sample with updated core_skill that uses function calling to
demonstrate
- Added a second sample that shows how to use function_calling with
non-sk functions.

This solves [this
issue](https://github.com/microsoft/semantic-kernel/issues/1069) where
native functions are not returning the expected result. In python,
return typehints are optional. However, the semantic kernel requires a
return typehint to determine how to handle the function. For that
reason, we're now enforcing return typehints and raising an exception
when one is not provided. This may break existing void functions but
none in our repo are affected.
Fixes#1069

## Summary
This pull request includes two sets of changes. First, it fixes the
return type annotations in three core skills: file_io_skill,
text_memory_skill, and wait_skill. Specifically, the write_async method
in file_io_skill and the save_async method in text_memory_skill now have
a return type of None, and the wait method in wait_skill now has a
return type of None. Additionally, the
import_native_skill_from_directory method in kernel.py has been
refactored to simplify the code. Second, this pull request adds error
handling for functions with no return type in the delegate inference
module. Previously, if a function did not specify a return type, the
DelegateType could not be inferred, leading to errors. This pull request
adds a check for functions with no return type and raises a
KernelException with an appropriate error message. Additionally, this
pull request includes some minor changes to unit tests for native
functions.
## Changes
- Fixed return type annotation for write_async method in file_io_skill
- Fixed return type annotation for save_async method in
text_memory_skill
- Fixed return type annotation for wait method in wait_skill
- Refactored import_native_skill_from_directory method in kernel.py
- Added error handling for functions with no return type in the delegate
inference module
- Added a check for functions with no return type and raised a
KernelException with an appropriate error message
- Made minor changes to unit tests for native functions

*Powered by [Microsoft Semantic
Kernel](https://github.com/microsoft/semantic-kernel)*
SKFunction has been excluded for now.
Handles issues arising due to many circular imports Update
DelegateInference to handle some cases where annotation is given as a
string to avoid circular imports like in FileIOSkill.

while implementing #1691, there was an idea that adding
`invoke_stream_async` on `SKFunction` is reasonable.
<img width="870" alt="image"

moved temporal streaming logic from `Kernel` to `SKFunction`
I didn't want to add new `DelegateTypes` like `InStringOutStreaming` for
minimal changes.
in most cases, `SKFunction` is initiated from `from_semantic_config` or
`from_native_method`.
Now, both functions will handle the 'delegate_stream_function' argument,
which will be used in `invoke_stream_async`

This allows us to import OpenAPI documents, including ChatGPT plugins,
into the Semantic Kernel.
### Description
<!-- Describe your changes, the overall approach, the underlying design.
These notes will help understanding how your code works. Thanks! -->
- The interface reads the operationIds of the openapi spec into a skill:
```python
from semantic_kernel.connectors.openapi import register_openapi_skill
skill = register_openapi_skill(kernel=kernel, skill_name="test", openapi_document="url/or/path/to/openapi.yamlorjson")
skill['operationId'].invoke_async()
```
- Parse an OpenAPI document
- For each operation in the document, create a function that will
execute the operation
- Add all those operations to a skill in the kernel
- Modified `import_skill` to accept a dictionary of functions instead of
just class so that we can import dynamically created functions
- Created unit tests
TESTING:
I've been testing this with the following ChatGPT plugins:
- [Semantic Kernel Starter's Python Flask
plugin](https://github.com/microsoft/semantic-kernel-starters/tree/main/sk-python-flask)
- [ChatGPT's example retrieval
plugin](https://github.com/openai/chatgpt-retrieval-plugin/blob/main/docs/providers/azuresearch/setup.md)
- This one was annoying to setup. I didn't get the plugin functioning,
but I was able to send the right API requests
- Also, their openapi file was invalid. The "servers" attribute is
misindented
- [Google ChatGPT
plugin](https://github.com/Sogody/google-chatgpt-plugin)
- [Chat TODO plugin](https://github.com/lencx/chat-todo-plugin)
- This openapi file is also invalid. I checked with an online validator.
I had to remove"required" from the referenced request objects'
properties:
https://github.com/lencx/chat-todo-plugin/blob/main/openapi.yaml#L85
Then I used this python file to test the examples:
```python
import asyncio
import logging
import semantic_kernel as sk
from semantic_kernel import ContextVariables, Kernel
from semantic_kernel.connectors.ai.open_ai import AzureTextCompletion
from semantic_kernel.connectors.openapi.sk_openapi import register_openapi_skill

google_chatgpt_plugin = {

}
todo_plugin_get = {

}
plugin = todo_plugin_get # set this to the plugin you want to try
logger = logging.getLogger(__name__)
logger.addHandler(logging.StreamHandler())
logger.setLevel(logging.DEBUG)
kernel = Kernel(log=logger)
deployment, api_key, endpoint = sk.azure_openai_settings_from_dot_env()
kernel.add_text_completion_service(
"dv", AzureTextCompletion(deployment, endpoint, api_key)
)
skill = register_openapi_skill(
kernel=kernel, skill_name="test", openapi_document=plugin["openapi"]
)
context_variables = ContextVariables(variables=plugin)
result = asyncio.run(
skill[plugin["operation_id"]].invoke_async(variables=context_variables)
)
print(result)

### Motivation and Context
To take advantage of APIs offered by most LLMs and to be in sync with
.NET SK, this PR introduces the ability to generate multiple text
completions or chat completions from a single prompt.
### Description
- Return type hint for `complete_async` and `complete_chat_async`
changed from `str -> Union[str, List[str]]`. The use of `Union` is the
proper way to indicate multiple return types prior to Python 3.10+. 3.10
supports the use of the `|` symbol, but since the Python SK is supported
on 3.8 and 3.9, I did not adopt the newer standard.
- `complete_async`, `complete_stream_async`, `complete_chat_async`, and
`complete_chat_stream_async` now support settings field
`number_of_responses` greater than 1. Previously only a value of 1 was
supported.
- **Note: hf_text_completion does not support streaming multiple
responses due to a limitation of TextIteratorStreamer. This feature
requires the ability to parse distinct responses from
TextIteratorStreamer.**
- Fixed a bug where `complete_async` was streaming single responses as
1D arrays, content now is simply a string.
### Example Usage
#### Setup
```
kernel = sk.Kernel()
# Configure OpenAI service
api_key, org_id = sk.openai_settings_from_dot_env()
oai_text_service = OpenAITextCompletion("text-davinci-003", api_key, org_id)
oai_chat_service = OpenAIChatCompletion("gpt-3.5-turbo", api_key, org_id)
# Configure Hugging Face service
hf_text_service = HuggingFaceTextCompletion("gpt2", task="text-generation")
# Configure Prompt
prompt = "what is the purpose of a rubber duck?"
# Configure Request Settings
text_request_settings_multi = CompleteRequestSettings(
max_tokens=100,
temperature=0.7,
top_p=1,
frequency_penalty=0.5,
presence_penalty=0.8,
number_of_responses=4
)
chat_request_settings_multi = ChatRequestSettings(
max_tokens=100,
temperature=0.7,
top_p=1,
frequency_penalty=0.5,
presence_penalty=0.8,
number_of_responses=4
)
```
#### Text Completion (Standard)
```
texts = await oai_text_service.complete_async(prompt, text_request_settings_multi)
i = 0
for text in texts:
print("Option " + str(i) + ": " + text)
i += 1
```
#### Streaming Text Completion
```
multi_stream = oai_text_service.complete_stream_async(prompt, text_request_settings_multi)
texts = [''] * text_request_settings_multi.number_of_responses
async for text in multi_stream:
i = 0
os.system('cls' if os.name == 'nt' else 'clear') # clear the screen for a better experience
print("PROMPT: " + prompt)
for option in text:
texts[i] = texts[i] + option
print("{0}: {1}".format(i, texts[i]))
i += 1
```
#### Chat Completion (Standard)
```
texts = await oai_chat_service.complete_chat_async([("user",prompt)], chat_request_settings_multi)
i = 0
for text in texts:
print("Option " + str(i) + ": " + text)
i += 1
```
#### Streaming Chat Completion
```
multi_stream = oai_chat_service.complete_chat_stream_async([("user",prompt)], chat_request_settings_multi)
texts = [''] * chat_request_settings_multi.number_of_responses
async for text in multi_stream:
i = 0
os.system('cls' if os.name == 'nt' else 'clear') # clear the screen for a better experience
print("PROMPT: " + prompt)
for option in text:
texts[i] = texts[i] + option
print("{0}: {1}".format(i, texts[i]))
i += 1
```
#### HuggingFace Standard Completion
```
texts = await hf_text_service.complete_async(prompt, request_settings_multi)
i = 0
for text in texts:
print("-----------------------------------")
print("Option " + str(i) + ": " + text)
i += 1
```
### Motivation and Context
Use of abstraction was not consistent in the python SK. This PR makes
the import and use of ABC consistent and removes unused file kernel.py.
### Description
- MemoryStoreBase derives from ABC - this properly sets its metaclass.
MemoryStoreBase itself should never be instantiated, only derived.
- RetryMechanism derives ABC, so should be named 'Base' like all other
derivatives of ABC in this repo.
- removed kernel_base.py, was made obsolete by
https://github.com/microsoft/semantic-kernel/pull/1015
### Motivation and Context
The separation of Kernel, KernelBase, and KernelExtensions is several
layers of unnecessary abstraction. This PR does not change any API or
kernel behavior - it just reduces the number of files and namespaces to
accomplish the same functionality.
### Description
- Removed the `semantic_kernel/kernel_extensions` namespace. Methods
that existed in this namespace now exist in kernel.py.
- Removed KernelBase - this abstract class implies that there are
multiple ways to instantiate SK. For Python, we expect only a single
type of Kernel to instantiated for all instances.
- Updated tests and imports to accommodate the above changes.
* Fix lint errors
* Bump version number
* Add retry loop to integration tests
* Enable all integration tests: some tests will fail if OpenAI/Azure are
throttling.
### Motivation and Context
KernelConfig isn't needed as it's less pythonic and is not used
independently from Kernel. This moves all its methods and members into
Kernel.
### Description
- Removed KernelConfig
- Put KernelConfig's methods and variables into Kernel
- Ran unit and end-to-end tests
- Did not run notebooks because they are out of date with the current
repo.

### Motivation and Context
This PR is a consistency update between the Python and .NET Semantic
Kernels.
**This PR does not contain any feature enhancements or improvements!**
### Description
- Replace terminology 'backend' with 'service'
- Move semantic_kernel.ai (semantic_kernel/ai) to
semantic_kernel.connectors.ai (semantic_kernel/connectors/ai)
### Motivation and Context
To make the Python SK more pythonic, combined all kernel.run_* methods
into a single method with optional parameters.
### Description
- Removed `kernel.run_on_vars_async()`
- Removed `kernel.run_on_str_async()`
- Added `SKContext`, `ContextVariables`, and string params to
`kernel.run_async()`
- Moved `run_on_vars_async()` logic to `run_async()` method
- Arranged method params so that required params come before optional
params.
- Updated tests and notebooks where applicable.
### Motivation and Context
This PR makes creating a kernel instance more pythonic. The builder
pattern is removed and the kernel is constructed using Kernel(...).
Work originally started with #137
### Description
- Removed kernel_builder.py.
- Instance creation pattern `kernel = sk.create_kernel() -> kernel =
sk.Kernel()`
- For notebook 6, there is no need to create a separate kernel for the
GitHub files. Changed to use a separate collection.

### Motivation and Context
In an effort to make the Python port more idiomatic, let's remove the
`Verify` class and the `./diagnostics` sub-module. There are many more
follow-on tasks to do here, but this is a good start (and already a
large enough change).
### Description
This PR does the following:
1. Removes the `Verify` class, and re-writes all instances of `Verify.*`
2. Adds a `validation.py` in the `./utils` sub-module to hand some of
the more complex cases from `Verify` (checking that skills/functions/and
function params have valid names)
3. Removes the rest of the `./diagnostics` sub-module (w/ a longer-term
goal of removing all/most of our custom exception classes and, instead,
using appropriate built-in error classes)
### Motivation and Context
The `python-preview` branch is under active development and many
docs/tests/examples are getting a bit out of sync. There are also a few
small cleanup chores/refactors to make _usage_ easier (e.g., to make
examples cleaner). I've grouped these small fixes (plus a few bug fixes)
into this "cleanup" PR.
### Description
This PR does the following:
1. Updates the out-of-date example in `README.md`
2. Fixes all 5 of the notebooks we support right now (1,2,3,4, and 6;
notebook 5 is planner, I've blanked out most of the code there so we
don't confuse people, especially as the planner API is changing)
3. Fixes a bug w/ `stop_sequences` in `(Azure)OpenAITextCompletion`
4. Fixes a bug introduced in our upgrades to the embeddings cosine-sim
check (we should add more thorough tests here)
5. Cleans up tests
6. Ensures end-to-end tests are all runnable
7. Fixes up the `kernel_extensions` to work more naturally (so that end
users can use them directly on the `kernel` object and get good
type-hinting)
### Motivation and Context
Right now, there are lots of Config classes in SK. This doesn't feel
very "pythonic" and can be a bit confusing at times. To reduce the
amount of indirection, this PR removes several config classes from the
Python port.
NOTE: this PR is also critical preparation for a large change to re-sync
with how C# SK handles multi-modality. I have changes ready for adding a
`./connectors` dir and syncing with the Text/Chat/Image/Embedding
support, but there's a few "prep" PRs I need to get through first.
### Description
This PR makes the following changes:
1. We remove the `(Azure)OpenAIConfig` classes (simplifying the code
related to creating/managing backends)
2. We remove the `./configuration` sub-directory and move the
`KernelConfig` class to the module's root dir (this mirrors the C#
version)
3. We re-tool the `KernelConfig` class to behave similarly to the
current C# version (again, this is prep for later changes RE
multi-modality)
4. We make corresponding updates across the code/tests now that we've
removed some config classes
In future PRs, it'd be great to also simplify:
1. `(Chat|Completion)RequestSettings`
2. `(ReadOnly)SkillsCollection` and related classes
3. Take a hard look at `ContextVariables` and `SKContext` (maybe
`ContextVariables` is just a `dict` in SK python)
### Motivation and Context
The C# Semantic Kernel has recently undergone an upgrade to its
`PromptTemplateEngine`. This brings Python back in line with the
semantics of Prompt Templates in C#.
### Description
Here, unlike the original port, I've tried to make things more
pythonic/idiomatic (instead of trying to directly mirror the C#
codebase). I've also brought over the corresponding unit tests (and
added some of my own as I was building/validating).
This PR provides a path to using the ChatGPT API in the Python Preview
of Semantic Kernel. In addition, this provides `Azure*` versions of many
existing models (so Python users can leverage Azure OpenAI).
I think that, in general, it may be worth considering how best to work
with models that have different modalities: now we have text
completions, embeddings, chat completions (and I'd imagine images/etc.
may be nice to support someday too).
Regardless, this PR provides a fast path to using the exciting new Chat
APIs from OpenAI with SK!
See the new `python/tests/chat_gpt_api.py` for a usage example.
### Motivation and Context
This PR simplifies `@sk_*` decorators while porting the core TextSkill
### Description
This PR is a first step at adapting the python codebase to be more
*pythonic*, it contains the following modifications :
1. Merged the decorators `@sk_function_context_parameter`,
`@sk_function_input` , `@sk_function_name` with `@sk_function`.
The decorators were replaced with new kwargs on `sk_function` : `name`,
`input_description`, `input_default_value`
2. The `name` kwarg is optional, the name of the method will be used if
none is provided.
3. Ported core skill - TextSkill
4. Added some pytest unit test for SK decorators and TextSkill
5. Changed how skills are imported in the kernel by using instance of
the class, not relying on static method anymore for the discovery.
e.g.
```
kernel.import_skill(TextSkill())
```
