加载.pkl文件后出现Python错误“ValueError：无法识别加载的数组布局”

下面的代码用于隔离林的培训过程，以便创建.pkl文件（您可以在此处查看链接scikit-learn.org/stable/modules/generated/...） . 生成.pkl文件后，我将它从ubuntu加载到raspbian OS . 但是，我遇到了这个错误“ValueError：无法识别加载的数组布局” . 谁能帮我这个？完成错误：

回溯（最近一次调用最后一次）：文件“oneclass_test.py”，第24行，在clf_one，stdSlr，voc，k = joblib.load（'oneclass.pkl'）文件“/usr/local/lib/python2.7 /dist-packages/sklearn/externals/joblib/numpy_pickle.py“，第575行，在load obj = _unpickle（fobj，filename，mmap_mode）文件”/usr/local/lib/python2.7/dist-packages/sklearn/ externals / joblib / numpy_pickle.py“，第507行，在_unpickle obj = unpickler.load（）文件”/usr/lib/python2.7/pickle.py“，第858行，在load dispatchkey文件”/ usr / local / lib / python2.7 / dist-packages / sklearn / externals / joblib / numpy_pickle.py“，第327行，在load_build中Unpickler.load_build（self）文件”/usr/lib/python2.7/pickle.py“，第1217行，在load_build setstate（state）文件“sklearn / tree / _tree.pyx”，第650行，在sklearn.tree._tree.Tree.setstate中（sklearn / tree / _tree.c：8406）ValueError：无法识别加载的数组布局
