XR-Transformer prediction step about pecos

[celsofranssa]

Trying to resolve the above error, I ensured that both X (training step csr_matrix) and Xt (prediction step csr_matrix) have the same number of features.

However, the following error has now occurred:

    raise ValueError("Query matrix does not have sorted indices!")
ValueError: Query matrix does not have sorted indices!

How can I get around this error?

Hi @celsofranssa, as the error indicates, your input sparse matrices need to have sorted indices.
