CUDA kernel failed : no kernel image is available for execution on the device, Error when running PyTorch model inside Google Compute VM
I have a docker image of a PyTorch model that returns this error when run inside a google compute engine VM running on debian/Tesla P4 GPU/google deep learning image:

CUDA kernel failed : no kernel image is available for execution on the device


This occurs on the line where my model is called. The PyTorch model includes custom c++ extensions, I'm using this model https://github.com/daveredrum/Pointnet2.ScanNet

My image installs these at runtime

The image runs fine on my local system. Both VM and my system have these versions:

Cuda compilation tools    10.1, V10.1.243

torch                     1.4.0                 

torchvision               0.5.0 

The main difference is the GPU as far as I'm aware

If I ssh into the VM torch.cuda.is_available() returns true

Therefore I suspect it must be something to do with the compilation of the extensions

This is the relevant part of my docker file:

I have already re-running this line from ssh in the VM:

TORCH_CUDA_ARCH_LIST="6.0 6.1 7.0" python setup.py install


Which I think targets the installation to the Tesla P4 compute capability?

Is there some other setting or troubleshooting step I can try?

I didn't know anything about docker/VMs/pytorch extensions until a couple of days ago, so somewhat shooting in the dark. Also this is my first stackoverflow post, apologies if I'm not following some etiquette, feel free to point out.

I resolved this in the end by manually deleting all the folders except for "src" in the folder containing setup.py

Then rebuilt the docker image

Then when building the image I ran TORCH_CUDA_ARCH_LIST="6.1" python setup.py install, to install the cuda extensions targeting the correct compute capability for the GPU on the VM

and it worked!

I guess just running setup.py without deleting the folders previously installed doesn't fully overwrite the extension
