PyTorch is not upgrading in conda environment

[mhadnanali]

I am a client user of my research lab server, There is PyTorch 1.3.1 is installed on the server but I want to use 1.8.0 with cuda 10.1.
So when I run the command.

"pip install torch-scatter torch-sparse torch-cluster torch-spline-conv torch-geometric -f https://data.pyg.org/whl/torch-1.8.0+cu101.html"
It says that requirements are satisfied, while when I check the version it says "Version 1.3.1"
Why this contradiction ?

I also tried to install it with conda command, but in that way, it don't install Cuda, seems like my only option is pip and it also is not working.

Take a look at the screenshot for all relevant details.

The pip install torch-scatter torch-sparse torch-cluster torch-spline-conv torch-geometric -f https://data.pyg.org/whl/torch-1.8.0+cu101.html command does not will install PyTorch. You have to manually install it following the guidelines here. In case you want to force an upgrade of certain packages, it's best to use pip install --upgrade torch-scatter ....

I installed PyTorch but it doesn't seem like working. Apparently, PyTorch is installed but "import torch_geometric or import torch_geometric.transforms" is still not working.
Error: OSError: libtorch_cpu.so: cannot open shared object file: No such file or directory

Error: OSError: /home/adnan/.local/lib/python3.8/site-packages/torch_sparse/_version_cuda.so: undefined symbol: ZN3c106detail12infer_schema20make_function_schemaENS_8ArrayRefINS1_11ArgumentDefEEES4

Is this a version issue or what? as my PyTorch is 1.7.1 but Pytorch geometric command had "torch-1.8.0+cu101",
if this is a version issue then how I am suppose to find the torch 1.7.1 with cuda 10.1?

Big Thanks for your help.

Note: nvcc --version and print(torch.version.cuda) version both are same.

For installing PyG for PyTorch 1.7.1, run:

pip install torch-scatter==2.0.7 torch-sparse==0.6.9 torch-cluster==1.5.9 torch-spline-conv==1.2.1 torch-geometric -f https://data.pyg.org/whl/torch-1.7.1+cu101.html
