I have encountered a difficulty.

I have encountered a difficulty as shown below, and I cannot find a solution online. Please help me with some guidance. Thank you very much.

ImportError: numpy.core.multiarray failed to import (auto-generated because you didn't call 'numpy.import_array()' after cimporting numpy; use 'numpy._import_array' to disable if you are certain you don't need it).

Hi,
Can you give the full stacktrace, provide your environment settings, package versions etc.
Where odes it happen? At training, inference, which part of the repo?

I encountered the same issue. Here's how I solved it: I reinstalled the pesq package in my conda virtual environment. The reason was that the package was not installed.

It's something like this:

It has mentioned about the error just like the earlier one.

Yes as @DIdididi0 suggested, this is related to the PESQ packages. Please install it via pip before running either inference or training.
