Numpy 2 compatibility

Opened this issue · 0 comments

When testing a fresh installation (July 2024) of PEPPAN by running provided example genomes a following error is returned:
AttributeError: module 'numpy.lib.npyio' has no attribute 'format'

This appears to be due to incompatibility with the latest Numpy release - 2.0 and later.
Manually downgrading Numpy to 1.26.4 appears to solve the issue.
