Is this with reference to #27815 ? I thought the plan on record was just to disable this on Windows...

@ezyang I can limit the check to just Windows, but can you think of any other 32-bit platform we might want to support?

So we are rejecting users to build that by themselves, right?

Yes, because 32-bit PyTorch build is currently not supported, but if user tried to build it using 32-bit runtime it fails with a confusing error message.

I might suggest elaborating the error message a bit. The most common reason why bit size is 32 bit is because you have 32 bit Python, but your system might actually be 64 bit, in which case the correct fix is to install 64 bit Python (which is what was the case for the issue people filed.)

I think it will more useful if we patch the v0.1.2 source so that it will present better message if users try to install a binary package with 32-bit Python on Windows.
