Google Cloud Function Gen 1 Deployment Failure
This is mostly for the community, because it took me quite a while to figure out.
I have a python 3.9 environment stateless Google Cloud Function using pytorch.  The initial deployment and function creation has no errors/issues.  Requirements.txt looks like this:
torch==1.10.2

However, when I edit even the smallest, innocuous change and save, the deployment fails with the error:
Build failed:
Collecting torch==1.10.2; Error ID: c84b3231

How do you redeploy with pytorch?

I still do not know the reason why installing pytorch on redeploy fails, but this is how I got Google Cloud Function to consistently redeploy without fail.  I directly input the specific version of PyTorch link: linux, cpu-based, version.

Go to the latest versions of PyTorch: PyTorch Latest Releases.
Search for the desired version (currently, the latest is 1.10.2).  I chose torch-1.10.2%2Bcpu-cp39-cp39-linux_x86_64.whl.
Copy link and paste in requirements.txt by replacing torch==1.10.2.

If anybody knows why Google Cloud Function Gen 1 rejects redeployment with the conventional distribution of torch, feel free to edit.
Hope this saves someone time.
