cpp_extension ninja subprocess error on Amazon EC2 server with CUDA 11.

[akokhlik]

Hi everyone,

I am encountering issues when installing VToonify on my Amazon ec2 Linux 2 server which has CUDA 11.

Here is a snippet of the issue that I see:
Traceback (most recent call last):
File "/home/ec2-user/anaconda3/envs/vtoonify_env/lib/python3.8/site-packages/torch/utils/cpp_extension.py", line 1516, in _run_ninja_build
subprocess.run(
File "/home/ec2-user/anaconda3/envs/vtoonify_env/lib/python3.8/subprocess.py", line 512, in run
raise CalledProcessError(retcode, process.args,
subprocess.CalledProcessError: Command '['ninja', '-v']' returned non-zero exit status 1.

The full error message can be found here. Error message

The output of conda list can be found here. Conda list

Any help would be greatly appreciated.

Thank you,
Artur
