matmul: Input operand 1 has a mismatch in its core dimension 0, with gufunc signature (n?,k),(k,m?)->(n?,m?) (size 10 is different from 1)

This error message suggests that there is a problem with the dimensions of the input matrices in a matrix multiplication operation. Specifically, the first input matrix has a mismatch in its first dimension, which should match the second dimension of the second input matrix.
The gufunc signature (n?,k),(k,m?)->(n?,m?) indicates that the first input matrix has shape (n,k), the second input matrix has shape (k,m), and the output matrix should have shape (n,m).
The "size 10 is different from 1" part of the error message suggests that the first input matrix has a size of 10 in its first dimension, while the second input matrix has a size of 1 in its second dimension. This is not compatible with the gufunc signature, which requires the first dimension of the first matrix to match the second dimension of the second matrix.
To fix this error, you need to ensure that the shapes of the input matrices are compatible with the gufunc signature. This may involve reshaping or transposing the matrices, or modifying the code that generates them.
