Error in google colab notebook

[abhijeetmanhas]

It was running fine, just 2-3 hours ago, but isn't working now. Probably there has been some updates on the github repositories used in this notebook.

Complete error log:

I found that default pytorch version on Google Colab is updated to 1.7.0 and the current pip package only supports pytorch 1.6 with cuda. I guess pip package will be updated at some point but tentative fix would be either forcing google colab to use Pytorch 1.6 reference or compiling pytorch3d from source code !pip install 'git+https://github.com/facebookresearch/pytorch3d.git@stable' , which is slow...

A relevant issue is here. https://github.com/facebookresearch/pytorch3d/issues/339

[ssssssssssss]

!pip install 'torch==1.6.0+cu101' -f https://download.pytorch.org/whl/torch_stable.html !pip install 'torchvision==0.7.0+cu101' -f https://download.pytorch.org/whl/torch_stable.html !pip install 'pytorch3d==0.2.5'

Please install this version instead the in-stock versions

[innat]

Though I install the above version at the very beginning, the error is still throwing. Any catch?

[abhijeetmanhas]

Remove the line which is installing pytorch3D again

Any help for this error ?

[mkskalai]

I solved the problem by following the INSTALL.md instructions of pytorch3d but installing cuda 10.1 instead of 10.2:

conda install -c pytorch pytorch=1.7.0 torchvision cudatoolkit=10.1

everything else just like in the instructions

[alex-treebeard]

I've just released nbmake which maintainers may find helpful here

[shunsukesaito]

I updated the comments in the google colab with two tentative fixes.

[TheDevelolper]

@shunsukesaito the fixes in the Google Colab do not seem to work.

I tried this but I'm still getting the same error:

!pip install 'torch==1.6.0+cu101' -f https://download.pytorch.org/whl/torch_stable.html
!pip install 'torchvision==0.7.0+cu101' -f https://download.pytorch.org/whl/torch_stable.html
!pip install 'pytorch3d==0.2.5'

# If you get an error in the next cell, you can instead try the following command (don't forget to comment out the one above!).
# Note that this error is caused by inconsistent cuda version for the pytorch3d package and pytorch in Colab environment.
# Thus, this issue may persist unless pytorch3d in the pip package is updated with the cuda version consistent with pytorch in Colab.
# Also please be aware that the following command is much slower as it builds pytorch3d from scratch.

# !pip install 'git+https://github.com/facebookresearch/pytorch3d.git@stable'

# You can try another solution below as well. This is also slow and requires you to restart the runtime.

# !pip install 'torch==1.6.0+cu101' -f https://download.pytorch.org/whl/torch_stable.html
# !pip install 'torchvision==0.7.0+cu101' -f https://download.pytorch.org/whl/torch_stable.html
# !pip install 'pytorch3d==0.2.5

@FacePalmDev you have to restart the runtime to make it work

[ChenChihYuan]

I am having the same issue, and have already tried to pip the alternative 3 lines. Still failed. Really cool project. Any idea about how to fix it? I am not that familiar with colab. Thanks

[ChenChihYuan]

Sorry for the comment above. I am quite new with colab. With this https://www.youtube.com/watch?v=WjvM3FcpId4&t=0s tutorial video, I understand how to make it works. The rendering parts should be changed to

!pip install 'torch==1.6.0+cu101' -f https://download.pytorch.org/whl/torch_stable.html !pip install 'torchvision==0.7.0+cu101' -f https://download.pytorch.org/whl/torch_stable.html !pip install 'pytorch3d==0.2.5'

Please install this version instead the in-stock versions

and ALSO we need to restart the runtime.

The other colab scripts provided by the youtuber mentioned above. Basically he did the same thing.

https://colab.research.google.com/github/derekphilipau/machinelearningforartists/blob/main/PIFuHD_Demo.ipynb

One small bug I had was in the upload file part, there's not pop-up window asking for photo path. And the reason is I am currently using Brave the browser.

In case someone have the same experience as I did.

""ERROR: pip's dependency resolver does not currently take into account all the packages that are installed.

why do i get this?

[aaparikh]

Even after following the mentioned steps, I am getting the following error. Please help me out.

Please explain what is lib.colab_util ?

I'm Also facing the same error i try all suggestion given below but the error didn't solved so please help me to figure out the solution

[innat]

@shunsukesaito Please take a look into this issue.

[spiritwhispers]

Did you guys figure anything out on this issue. I am stuck and don't know what to do. Thanks.

[Manojooo7]

Sorry didn't find anything
