使用 numpy.save 保存并使用 pickle.load 加载时出错

Question

I've saved a simple numpy array by doing:

numpy.save(filepath, anarray)

I'm now trying to retrieve it using pickle (I don't want to switch to numpy.load because the code has to be flexible), but I get:

atuple = pickle.load(open(filepath, 'rb'))

_pickle.UnpicklingError: STACK_GLOBAL requires str

Answer 1

Numpy and pickle use different file formats. There's no reason to expect that you should be able to unpickle an array saved using np.save . If you need to be able to load things with pickle, you should save them with pickle.
