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

Have you solved this error ? @akokhlik I'm also facing the similar issue while implementing this model. @williamyang1991 your help will be greatly appreciated

@williamyang1991 As I remember there was CUDA version problem

[MahrukhAliKhan]

@akokhlik Do you remember which CUDA version solved your problem ? also your pytorch and python version? Did you face this issue on Windows or on Linux?

[akokhlik]

@williamyang1991 My server was Linux. Now this server does not exist and I do not remember the versions.

@akokhlik just tested on CUDA 10.1 and I have left my original university and that server is not available now to me.
@MahrukhAliKhan Since your problem is from model.stylegan.op, I think you can just try the CPU compatible version instead,
See stylegan.op_cpu
