Dify version

0.9.1

Cloud or Self Hosted

Cloud

Steps to reproduce

  1. Create app from importing DSL file and the content of DSL file is as follows:
app:

    viewport:
      x: -150
      y: 113
      zoom: 1
  1. Enter the following information in the chat text box of the app:
What's the following formula?
$$1.5 , \text{m} \leq h_{UE} \leq 13.5 , \text{m}$$ 和 $$15 , \text{m} \leq h_{BS} \leq 35 , \text{m}$$
  1. The answer of the app is as follows:
The formulas you've provided define the range of acceptable heights for two entities, likely referring to an "UE" (User Equipment) and a "BS" (Base Station), in meters.

Specifically:

For the UE (User Equipment): The height $$h_{UE}$$ must be within the range from 1.5 meters to 13.5 meters.
For the BS (Base Station): The height $$h_{BS}$$ must be within the range from 15 meters to 35 meters.
These constraints could be relevant in scenarios such as wireless communication systems where the height of devices can affect signal strength and coverage.

In addition, I tried the 0.7.0 version of dify, deployed with docker.

As can be seen from the test above, the latest version of dify cannot properly render the formula of the markdown file.

✔️ Expected Behavior

The latest version of dify can properly render the formula of the markdown file.

❌ Actual Behavior

The latest version of dify cannot properly render the formula of the markdown file.

@dosubot[bot] commented on GitHub (Oct 10, 2024):

There are some related discussions and issues regarding formula rendering in Dify:

  1. A similar unsolved discussion about integrating MathJax for rendering mathematical formulas in the Dify chat client [1].
  2. A closed issue requesting video playback and formula rendering in the front-end, but it was closed without a solution [2].

For rendering formulas, Dify uses remark-math and rehype-katex libraries. The configuration for these libraries in Dify is as follows:

<ReactMarkdown
  remarkPlugins={[[RemarkGfm, RemarkMath, { singleDollarTextMath: false }], RemarkBreaks]}
  rehypePlugins={[
    RehypeKatex,
    RehypeRaw as any,
    // Additional plugin logic
  ]}
>
  {latexContent}
</ReactMarkdown>

Ensure that these configurations are correctly set up in your environment. If the issue persists, it might be worth checking if there have been any changes or updates in the libraries or configurations between versions 0.7.0 and 0.9.1 that could affect rendering [3].

I found that the formula rendering of the latest version of dify (0.9.2) is slightly defective.
If the large model outputs the following formula:

[
D=\left\lceil \frac{2N_{R E}}{N_{M A X}}\right\rceil,
]

the dify web page cannot be output normally.

If the large model outputs the following formula:

D=\left\lceil \frac{2N_{R E}}{N_{M A X}}\right\rceil,

the dify web page can output normally.
