Installation error with pyx

[jykr]

Copying error report from Elijah Login Mena @bwh

just want to let you know I had a minor issues installing bean on my computer yesterday. What worked for me was adding the following two lines to the beginning of the
CRISPResso2Align.pyx
file:

from numpy cimport import_array
import_array()

Otherwise I got the following error message:

>>>

 import (auto-generated because you didn't call 'numpy.import_array()' after cimporting numpy; use '<void>numpy._import_array' to disable if you are certain you don't need it).

Seems to be related to numpy version (tensorflow/tensorflow#559), please reopen if the update does not resolve the issue (without modifying CRISPResso2Align.pyx)

This error happens with unspecified bases in FASTQ, leading to alignment score over/underflow. Currently bean only supports A/C/T/G for bases. If you need to accommodate special bases, please edit output_path/.aln_mat.txt (

crispr-bean/bean/mapping/GuideEditCounter.py

Line 248 in fb67667

self.output_dir + "/.aln_mat.txt",

).
