Bug: AttributeError: module 'numpy' has no attribute 'object'.

[mazin01]

What happened?

I'm trying to convert a model that I fine tuned in python to tensorflow js format to use it in the web.

the fine tuned model folder has the following files:

• config.json
• generation_config.json
• model.safetensors
• special_tokens_map.json
• tokenizer_config.json
• tokenizer.json

I followed the same instructions for converting it using both tensorflowjs_convertor and tensorflowjs_wizard its all returning the same error bellow.

Relevant code

## command line code 1

tensorflowjs_converter \    --input_format=tf_saved_model \    --output_node_names='finetuned_task_to_json_model' \    --saved_model_tags=serve \    ./llm-testing/task_to_json_fine_tuned_model \    ./llm-testing/task_to_json_fine_tuned_tfjs_model


## command line code 2
tensorflowjs_wizard

Relevant log output

`np.object` was a deprecated alias for the builtin `object`. To avoid this error in existing code, use `object` by itself. Doing this will not modify any behavior and is safe. 
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
    https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations. Did you mean: 'object_'?

Hi @mazin01,

Apologies for the delayed response.

This looks more like a tensorflowjs issue than anything to do with tensorflow_hub. I found this resolved issue that looks similar to your situation:

tensorflow/tfjs#8030

tl;dr - it looks Windows is not supported for some tensorflowjs workflows

For future questions on tensorflowjs, I'd recommend creating an issue over on that repository.

Thanks, and happy modeling!
