Will not compile on GCC 11.1.0, CUDA 11.3

[norabelrose]

I've been trying to build this package for the last two nights to no avail. Every time I run python setup.py install, I get a big wall of compiler warnings indicating that it's not allowed to call __host__ functions from __host__ __device__ functions, followed by a few errors:

GCC indicates that this invalid template instantiation is required from torchcule/backend.cu:44:21, although the chain of dependencies linking that line of code to the final error is way too long and complex for me to understand. I've attached the entire stderr & stdout output from the compiler to this post. Any help toward solving this issue would be greatly appreciated.

@sdalton1, @ifrosio do you have any solution to this issue? And in general how to run CuLE with the latest PyTorch?

[Rohan138]

Hi there-I got it to work on my laptop (GTX 1650 Ti, CUDA 11.3, PyTorch 1.11.0) by fixing the following lines in setup.py:

codes = [arch[-2:] for arch in gpus]
arch_gencode = ['-arch=sm_' + codes[0]] + ['-gencode=arch=compute_{0},code=sm_{0}'.format(code) for code in codes]

You might also want to run it with python setup.py install --fastbuild to reduce the build time.

@ifrosio, @sdalton1 any updates on the issue? On how to build and run CuLE on Amper GPUs?

I got more errors:

I can't reproduce this error on my machine. I am compiling on Ubuntu 20.04.4, torch 1.12.0, gcc 9.4.0 and the cule main branch. I tried recompiling using an older version the cuda toolkit, version 11.3, from the dockerfile but that also worked on my machine. If anyone has a Dockerfile to generate the failure with the configured software that would help a lot.

Thanks @sdalton1 I just installed the latest ubuntu ( 22.04 I think). Looks like it is related to the wrong gcc version.
Will try to solve it using this link: https://linuxconfig.org/how-to-switch-between-multiple-gcc-and-g-compiler-versions-on-ubuntu-20-04-lts-focal-fossa
