How to Resolve NameError: name ‘_C’ is not defined in PyTorch on Linux
If you’re working with PyTorch on a Linux system and encounter the error NameError: name ‘_C’ is not defined, you’re not alone. This issue commonly arises due to problems with the PyTorch installation, and understanding how to resolve it can save you a significant amount of time and frustration.
The Problem: NameError: name ‘_C’ is not defined
The error NameError: name ‘_C’ is not defined typically indicates that the PyTorch library cannot find a compiled extension module known as _C. This can happen for several reasons, including:
Incomplete Installation: If PyTorch was not installed correctly, the _C module may be missing.
Version Mismatch: Using an incompatible version of PyTorch with your Python environment.
Corruption during Installation: Files might have been corrupted during the download or installation process.
Steps to Resolve the Error
Here are the steps to resolve this issue effectively:
Verify PyTorch Installation
Before diving into complex troubleshooting, ensure that PyTorch is installed properly. You can check this by running:

Build from Source (Advanced)
If the standard installation methods do not resolve the issue, you might need to build PyTorch from source. This approach is more advanced but can provide a tailored solution for your system. Follow the official build instructions available on the PyTorch repository.
Summary
The NameError: name ‘_C’ is not defined error in PyTorch on Linux can be a stumbling block, but it is typically resolvable by verifying the installation and ensuring compatibility. If these steps don’t resolve the problem, building from source remains an option. Following these guidelines should help you get back on track with your PyTorch projects.
Happy coding!
