[jetson]jetson上报错from numpy.lib.arraypad import _validate_lengthsImportError: cannot import name ‘_

报错：

Traceback (most recent call last):
  File "server.py", line 6, in
    from TaskManager import *

    from numpy.lib.arraypad import _validate_lengths
ImportError: cannot import name '_validate_lengths'
解决放方法：

sudo vi /usr/lib/python3/dist-packages/skimage/util/arraycrop.py

修改如下：屏蔽from numpy.lib.arraypad import _validate_lengths然后加入

#from numpy.lib.arraypad import _validate_lengths
from distutils.version import LooseVersion as Version
old_numpy = Version(np.__version__) < Version('1.16')
if old_numpy:
    from numpy.lib.arraypad import _validate_lengths
else:
    from numpy.lib.arraypad import _as_pairs
还有一种方法就是更换Numpy版本
