Python skimage.io

Question

我正在尝试使用python（导入库）运行此脚本

导入skimage.io

But i get  the following error 
Traceback (most recent call last):
  File "E:\seo_dwarf\chl_scripts\telika\ship_detection.py", line 2, in <module>

  File "C:\Python27\lib\site-packages\dask\bytes\compression.py", line 31, in <module>
    compress['snappy'] = snappy.compress
AttributeError: 'module' object has no attribute 'compress'

但是当我只是闲置地导入skimage.io时，我不会收到任何错误。

有什么办法解决错误吗？
