I got this error, do u know why?

I reckon it could be related to the "batch_first" argument in a relatively newer version of torch. You can try to remove the two "permute" operations in TextEncoder's forward function at model/maxvqa.py:27 and 29

+1 Did you end up find a way of resolving this issue and running the demo?

from explainablevqa.

Follow the instructions the repo gives for open_clip installation and you should not get this error. If you use pip install open-clip-torch you would get this error. They modified OpenClip.

from explainablevqa.

For reference, yes the installation of open_clip was the issue, but it was caused by the sed command used in the installation not working exactly as described by the documentation on macOS. Changing the command to
sed -i "" "92s/return x\[0\]/return x/" src/open_clip/modified_resnet.py
made this work for me (or you can just manually edit line 92 of modified_resnet.py to remove the square brackets).

Hello, why did I remove the square brackets on line 92 and still report shape error?
git clone https://github.com/mlfoundations/open_clip.git
cd open_clip
sed - i'92s/return x \ [0 ]/return x/'src/open_clip/modified_resnet.py
pip install - e.
Did you follow the steps in the README to install open_clip? Is there any other solution to this shape error problem?

from explainablevqa.

Not sure if this is just a pasting error in your question but if you're using the above command exactly as you've written there the sed command is written incorrectly, you either want:

sed -i "92s/return x\[0\]/return x/" src/open_clip/modified_resnet.py (original)
or
sed -i "" "92s/return x\[0\]/return x/" src/open_clip/modified_resnet.py (what I laid out above for macos)
then
pip install -e .
