Example script hangs without output

Hi Graphormer Team - thanks for this excellent codebase! I am opening a new issue because two similar issues have been previously closed. They are https://github.com/microsoft/Graphormer/issues/100 by @skye95git and https://github.com/microsoft/Graphormer/issues/99 by @mswzeus.

Bug

In short, despite carefully following the Graphormer installation instructions, there is no response at the console after running bash zinc.sh and interrupting the script produces a File "<frozen importlib._bootstrap>", line 107, in acquire error message.

Failed Solutions

In https://github.com/microsoft/Graphormer/issues/99, it was suggested that pip uninstall setuptools would fix the issue; however, this was not the case. Rather, running bash zinc.sh now throws terminate called after throwing an instance of 'std::bad_alloc' (which is fixed by reinstalling setuptools).

From @zhengsx in https://github.com/microsoft/Graphormer/issues/100:

We notice that similar problems occur recently, and a guess is that some recent upgrades of library lead to this problem. We're working on this problem, and maybe you can try to modify the version of cuda/torch, cu110 is recommeded.

Unfortunately, downgrading to torch.version.cuda==10.2 did not fix the issue either (i.e., bash zinc.sh still hangs). Should I find a solution, I will follow-up on this thread for future reference.

Start by reproducing the hang with bash zinc.sh after following the Graphormer installation instructions, then compare the reported setuptools and PyTorch/CUDA versions with issues #99 and #100. Done means identifying the dependency or environment cause and documenting or implementing a verified fix that lets the script produce output without the reported errors.
