Hi all, I am new to PyTorch.
Just recently installed it on my laptop with GeForce GT 550M card.
pytorch-cpu install and runs with no problems. Can’t install the latest version of Cuda, because it says, your GPU is two old ( I installed cuda 9 separately and it’s OK ). One of the participants here advised to install pytorch with lesser version of cuda using
**conda install pytorch torchvision cuda80 -c pytorch**
This time installation was OK and my example actually started in PyCharm , but pretty soon it failed with Error message that my card supports only Cuda 2.1
Few questions:


Is there anyway to reach to PyTorch developers , customer support etc, or the ONLY way is to publish questions on this forum ?


How does CudNN determine which cuda version is supported by my GPU and is it possible to make this check to be ignored by setting some option/variable ? My GPU is indeed old, but as I mentioned cuda 9 installed separately works just fine.


If I install PyTorch from source and link it with Cuda 9 I already have, would it be staill failing inside CudNN on version vs GPU test ?


Thanks a lot
