Fix FileNotFoundError

✅ Solution

FileNotFoundError in PyTorch tests usually means the test is trying to access a file that doesn't exist at the expected location. This often happens when a test depends on data files not being correctly created or copied during the build/test process or when the test assumes a specific working directory. To fix it, ensure any required data files are created/copied to the correct location before the test runs, and explicitly set the working directory if necessary using `os.chdir()` or by providing the full path to the file.
