Einops pattern should be valid

scientific-computing

This rule raises an issue when an incorrect pattern is provided to an einops operation.

Why is this an issue?

How can I fix it?

More Info

The einops library provides a powerful and flexible way to manipulate tensors using the Einstein summation convention. The einops uses a different convention than the traditional one. In particular, the axis names can be more than one letter long and are separated by spaces.
