Matrix dimensions must agree

This error message usually occurs when trying to perform an operation between arrays or matrices with incompatible dimensions. For example, if you try to add two matrices with different sizes, the operation will not be possible and this error message will be displayed.

To resolve this error, you should check the dimensions of the arrays or matrices involved in the operation and ensure that they are compatible. This may involve transposing one of the matrices, or reshaping them to have the same dimensions.

If you are still having trouble resolving this error, please provide more information about the specific operation you are trying to perform and the dimensions of the arrays or matrices involved.
