Trigger conditions err_info->Nutterances < 1

[luyan66]

    if (err_info->Nutterances < 1)
    {
        /*printf ("Processing error!\n");*/
        /*exit (1);*/
        PyErr_SetString(PyExc_RuntimeError, "processing error!");
    }

Log print warnings.warn('Processing Error! return NaN........')
use older version, i see it stop at conditions err_info->Nutterances < 1 processing error! WHY?
but if i change metric="pesq" to metric="" ，training is ok!

DeepComplexUNet use this pesq as it's metric
