Hi! I’m trying to install PyTorch on my Ubuntu 18.04. However, I found the 1.5.1(stable) is the only download version on the website 2. Then I jumped into the previous version 1 page but still cannot find this one (the latest is V1.2.0). May I ask is there any way I can install PyTorch 1.5.0 or downgrade to it? My system details are:

OS: Ubuntu 18.04
Python version: 3.7.7
PyTorch version now: 1.5.1
CUDA/cuDNN version: 10.1
GCC version: 7.5.0
Driver version: Nvidia 440

Thank you a lot for your time in advance!

(Here is a little bit more details about my motivation for downgrading. 1.5.1 version works perfectly on my system. However, when I try to install an open-source library PyTorch Geometric, it showed the error:
Failed to build wheel for torch-scatter: ERROR: Command errored out with exit status 1.
The authors say it may cause by PyTorch version and GCC version. ISSUE here 12. Hence I plan to use the PyTorch 1.5.0 to match it. If you have any idea why this problem happens please feel free to let me know. Thank you a lot!)
