Overview of Assertion Error with Torch and CUDA:

The Assertion Error “Torch not compiled with CUDA enabled” occurs when attempting to execute CUDA-specific code on a system that does not have the necessary CUDA libraries installed or when the PyTorch installation itself was built without CUDA support. This error prevents the use of GPU acceleration, resulting in slower computations on the CPU.

Understanding Compilation with CUDA Enabled:

Compilation with CUDA enabled refers to the process of building PyTorch with CUDA support. CUDA is the parallel computing platform and API model created by NVIDIA, which allows developers to leverage the power of NVIDIA GPUs for deep learning computations. When PyTorch is compiled with CUDA enabled, it becomes capable of offloading computations to the GPU, resulting in significant speedups.

Possible Causes of Assertion Error:

1. CUDA Libraries Not Installed: The most common cause of the Assertion Error is the absence of CUDA libraries on the system. PyTorch requires these libraries to be installed before it can utilize the GPU. Without them, the Torch installation will default to CPU-only mode.

2. Incompatible CUDA Version: If the installed CUDA version does not match the version for which PyTorch was built, compatibility issues may arise. This can lead to Assertion Errors when attempting to execute CUDA-specific code.

Resolving Assertion Error: Step-by-Step Guide:

1. Check CUDA Availability and Compatibility: First, ensure that CUDA is correctly installed on your system. You can do this by checking whether the “torch.cuda.is_available()” function returns “True”. Additionally, verify that the installed CUDA version matches the version required by your PyTorch installation.

2. Rebuilding Torch with CUDA Support: If CUDA is available and compatible, but still encounter the Assertion Error, rebuilding PyTorch with CUDA support may be necessary. This process involves recompiling the library with the appropriate CUDA configurations. Detailed instructions can be found in the official PyTorch documentation.

Troubleshooting Common Issues:

1. PyTorch Not Compiled with CUDA Enabled in PyCharm: If you encounter the Assertion Error in a PyCharm IDE, ensure that the correct PyTorch environment with CUDA support is selected. Verify the Python interpreter settings and make sure it corresponds to the CUDA-enabled version of PyTorch.

2. torch.cuda.is_available() Returns False: If “torch.cuda.is_available()” consistently returns “False,” it indicates that PyTorch cannot find the CUDA toolkit installation. Make sure that CUDA is correctly installed, and the respective environment variables are set up.

3. Mac Torch Not Compiled with CUDA Enabled: Mac systems have certain limitations regarding CUDA support. Ensure that your Mac version is supported by the CUDA toolkit, and follow the official CUDA installation guide for Mac to ensure proper configuration.

4. How to Enable CUDA in PyTorch: To enable CUDA support in PyTorch, the library needs to be compiled with CUDA configurations during the installation process. Make sure to follow the instructions specific to your operating system and CUDA version from the PyTorch website.

5. Downloading PyTorch with CUDA: If you are starting from scratch, ensure you download the correct PyTorch version pre-built with CUDA support for your system. This avoids the need for manual compilation and offers an easier setup process.

6. CUDA Not Available – Defaulting to CPU Note: If you encounter a statement like “CUDA not available – defaulting to CPU” during the execution of PyTorch code, it indicates that the Assertion Error occurred, preventing GPU utilization. Follow the aforementioned steps to address this issue.

Conclusion:

The Assertion Error “Torch not compiled with CUDA enabled” indicates a lack of CUDA support in your PyTorch installation, leading to slower computations on the CPU instead of benefiting from GPU acceleration.
