I’m new to pytorch. Yesterday, I installed pytorch on our server since source code. Before installation, I have to solve the problem of cuda version and cudnn version. Previously, our server’s cuda version is 8.0, while cudnn version is 5.1. So that the latest pytorch cannot be installed successfully, it needs cudnn version to be above than 6.0. However, some of my classmates installed pytotch on the same machine(cuda 8.0 and cudnn 5.0) with command pip successfully. From the command   It seems that pip command does not pay attention to cuda and cudnn version. I don’t know whether can we install pytorch successfully through conda command line.
So can anyone tell me what the difference between command installation and source code installation? Does  command line just pay attention to cuda version and ignore cudnn version? Thank you.
