ImportError：无法导入名称_remove_dead_weakref-运行python script.py时没有错误，从bash shell脚本中运行script.py时错误

Question

I am trying to import a package that requires sklearn. This is in a test script named script.py. When I run: python script.py allele_1 , I do not get an error. However, when I include this command inside a bash shell script as follows:

#!/bin/bash
allele=($(ls $1 | grep H))
python script.py $allele

I get the following error

File "/home/jhuang/miniconda2/lib/python2.7/site- 
packages/mhcnuggets/src/dataset.py", line 12, in <mod

from _weakref import (
ImportError: cannot import name _remove_dead_weakref

I've seen similar questions, but have not seen a definitive answer, nor have I seen any question in the context of command line vs shell script execution. Any help would be greatly appreciated!

Answer 1

This issue is probably you have installed python2 with homebrew which is conflicting with system python version. Try uninstalling python@2 homebrew version and you should be good to go.

brew remove python@2 --ignore-dependencies
