Error installing --bowtie2db

Hello all,

After installing Metaphlan using Anaconda I cannot install the database bowtie2db. I get this message:

metaphlan --install --bowtie2db /home/Documents/
ValueError: numpy.ndarray size changed may indicate binary incompatibility. Expected 88 from C header, got 80 from PyObject.

Version used:
Numpy: 1.19.4

Can someone help me?


I never encountered this kind of error with MetaPhlAn, have you tried to perform a clean installation using Python 3.7?

Thanks. Installing with Python 3.7 fixed the issue
