run error: No module named 'ninja'

[shuxjweb]

I have installed ninja. I have also tried several pytorch versions, e.g., 0.4.0 / 1.0.1 / 1.2.0 / 1.6.0 / 1.7.1. It always report the below errors. I do not know how to run this code.

have you solved this problem? I met same error too.

[aeoleader]

you need to install ninja before running the script

[kaniskgautam]

ninja is already installed

I also have the same problem. I have installed pytorch1.10, ninja 1.8.2, cuda 11.3. But still cannot run the program.

Traceback (most recent call last):
  File "/home/juneshi/anaconda3/envs/pytorch/lib/python3.8/site-packages/torch/utils/cpp_extension.py", line 1717, in _run_ninja_build

    raise CalledProcessError(retcode, process.args,
subprocess.CalledProcessError: Command '['ninja', '-v']' returned non-zero exit status 1.

The above exception was the direct cause of the following exception:

What is the ninja version? Please run the following command and check.

ninja --version

Ninja is required to load C++ extensions
sudo apt-get install ninja-build
This solved my problem.

请问解决了吗，我也遇到这个问题了

[robinsonmhj]

you can also use conda to isntall ninja-build. Here is the command
conda install ninja-build -c refractor
