@dosubot[bot] commented on GitHub (Jul 12, 2024):

The error you're encountering suggests that the input format for the "moondream" model's vision prediction is incorrect. Specifically, the value for <DETAIL.LOW: 'low'> should be a string, a list/tuple of strings, or a list/tuple of integers.

To resolve this, ensure that your input adheres to the required format for vision predictions. The "moondream" model requires images as input, which can be uploaded either locally or via URL. Additionally, the model can operate in both high and low resolution modes. Here is an example of how to structure your input:

{
  "function_call": {
    "name": "vision_prediction",
    "arguments": {
      "image": "URL_or_local_path_to_image",
      "resolution": "low"  // or "high"
    }
  }
}

Make sure to replace "URL_or_local_path_to_image" with the actual path or URL of your image and set the "resolution" to either "low" or "high" as required.

If the error persists, double-check the documentation for any additional input format requirements specific to the "moondream" model [1].
