ModuleNotFoundError: No module named 'aqt' about vision_transformer HOT 4 OPEN

Thanks for the kind reply.

Unfortunately, I think the error is not transient. I also tried the colab on fresh Colab VMs for several times, but the error always exits:

Since I'm using ViT models and the error seems to only appear when importing LiT models, I commented the lines about LiT in models.py (line 15, 28, 37 and 38) to bypass the error.

from vision_transformer.

I just tried
https://colab.research.google.com/github/google-research/vision_transformer/blob/main/vit_jax.ipynb
on a fresh Colab VM and !pip install -qr vision_transformer/vit_jax/requirements.txt completed without errors.

Maybe the error was transient?

You can specify a specific commit like flaxformer@git+https://github.com/google/flaxformer#5400cce007f3141c7f223a11846a2093b03a3588 (from their history) if you want to install an older version:

from vision_transformer.

this error happens to me as well when using a copy of https://colab.research.google.com/github/google-research/vision_transformer/blob/main/vit_jax.ipynb @ZigeW 's solution bypasses the error, but removes the ability to use the LiT models I guess.

I tried out the specific commit fix in vision_transformer/vit_jax/setup.py by @andsteing and it does not work unfortunately, it throws the same error

install_requires = [
    'absl-py',
    'clu',
    'einops',
    'flax',
    'flaxformer @ git+https://github.com/google/flaxformer#5400cce007f3141c7f223a11846a2093b03a3588',
    'jax',
    'ml-collections',
    'numpy',
    'packaging',
    'pandas',
    'scipy',
    'tensorflow_datasets',
    'tensorflow_probability',
    'tensorflow',
    'tensorflow_text',
    'tqdm',
]

So I guess commenting out the lines are the way forward for now?

Ok, the problem is actually in the latest release of the aqtp package: google/aqt#196

You can fix this by specifying !pip install aqtp==0.1.0 at the top of the Colab.

(PR fixing this repo is pending...)
