How to Fix RuntimeError: Couldn’t Install ‘torch’

The RuntimeError: Couldn’t Install ‘torch’ error occurs when there is a problem installing the ‘torch’ library, which is required for PyTorch, a popular machine learning library.

Causes of the RuntimeError

1. You have insufficient permissions to install the library.
2. It conflicts with an existing installation of ‘torch’ or other dependencies.
3. It is an incompatible system or environment.
4. Network connectivity issues.
5. The current Python version is not compatible with the ‘torch’.

Reproduce the error

import sys
import os

# Check if user is root
if not os.geteuid() == 0:
  sys.exit("\nYou must be root to run this script.\n")

os.system("pip install pytorch")
# Check if installation was successful
import torch

# If the import fails, raise a runtime error
if not torch:
  raise RuntimeError("Couldn't Install 'torch'")

The above code checks if the script’s user is root and then attempts to install PyTorch using pip.

If the installation fails, it raises a RuntimeError with the message “Couldn’t Install ‘torch'”.
