How to check which PyTorch version is installed?

To check which version of PyTorch is installed, you can use the __version__ attribute of the torch module. Here’s an example:

import torch

print(torch.__version__)

Output:

1.9.0

In the example above, torch.__version__ returns the version number of PyTorch that is currently installed.

Alternatively, you can also use the command pip show torch in the command line to see the version number of PyTorch that is installed using pip.

pip show torch

Output:

Name: torch
Version: 1.9.0
Summary: Tensors and Dynamic neural networks in Python with strong GPU acceleration
...

In summary, to check which version of PyTorch is installed, use either the __version__ attribute of the torch module, or use the command pip show torch in the command line.
