ImportError: cannot import name '_validate_lengths' from 'numpy.lib.arraypad'的解决办法

在升级了numpy之后sklearn-image的引用报告了以下错误：

Traceback (most recent call last):
  File "scripts/demo_5.py", line 15, in 
    from predictors.recon1_predictor import Recon1Predictor

ImportError: cannot import name '_validate_lengths' from 'numpy.lib.arraypad' (/home/users/bingqian.geng/anaconda3/lib/python3.7/site-packages/numpy/lib/arraypad.py)

这个问题的解决办法是

pip install numpy==1.15

原因是，在numpy升级的时候这个函数竟然重写了，虽然一般的调用没有什么毛病，但是sklearn-images调用了一些较为底层 的接口就导致了这个问题。
GitHub numpy更改记录：https://github.com/numpy/numpy/commit/a4b96ad7649281de2c3a41292fcbab4c77c0743d#diff-4fcddc9140fbe901655b3e1bd484205c

该函数已经改名为了下面这个：
