failed running python setup.py build develop for mega.pytorch

[LilyDaytoy]

I followed install.md
when running command
python setup.py build develop

my nvcc --version is cuda 10.1
I tried
conda install pytorch==1.4.0 torchvision==0.5.0 cudatoolkit=10.1 -c pytorch
conda install pytorch==1.5.0 torchvision==0.6.0 cudatoolkit=10.1 -c pytorch
conda install pytorch==1.7.0 torchvision==0.8.0 torchaudio==0.7.0 cudatoolkit=10.1 -c pytorch
all cannot

Could you help me check what is going on? Thanks a lot!

The current codebase only works with pytorch 1.3.0 (or lower), as mentioned in the INSTALL.md. So you may try a older version of pytorch.

[LilyDaytoy]

Hi! I tried using exactly conda install pytorch=1.3.0 torchvision cudatoolkit=10.0 -c pytorch, and I also change my nvcc version to 10.0, but still failed like this

[LilyDaytoy]

my versions:
nvcc: 10.0
gcc: 5.3.0
pytorch 1.3.0

Also for

cd cocoapi/PythonAPI
python setup.py build_ext install

I also encountered this issue: error: command '/mnt/lustre/share/gcc/gcc-5.3.0/bin' failed: Permission denied
so I used

conda install -c conda-forge pycocotools

is it ok?

[Scalsol]

It seems that it's a permission issue with your gcc directory. So maybe try to update the folder permissions by chmod.

[LilyDaytoy]

Ohh, thanks a lot! I found the error was actually because of my gcc dir, I add CC=gcc before python setup.py build develop, and the problem is solved.
But I encountered another problem, when inferencing the model, there is an error AttributeError: module 'torch.cuda' has no attribute 'amp' (apex/apex/transformer/amp/grad_scaler.py line 21), I searched online and they say amp is only available after pytorch 1.6, but the repo only support pytorch 1.3 and lower, so is there any way to solve this problem?
Thanks for your patience :D
