Scikit-learn joblib / zlib错误

Question

I ran into the following error when trying to load a .pkl file using joblib.

    self.name = joblib.load(
        os.path.join(BASE_DIR, '../relative/directory/%s.pkl' % name)
    )

The above code yields the following error.

 File "/usr/local/lib/python2.7/dist-packages/sklearn/externals/joblib/numpy_pickle.py", line 68, in read_zfile
    data = zlib.decompress(file_handle.read(), 15, length)
zlib.error: Error -3 while decompressing data: invalid distance too far back

Has anyone run into this issue before?

Answer 1

这意味着压缩数据在整个过程中的某处被破坏了。
