无法加载包含腌制数据的文件-Python .npy I/O [英] Cannot load file containing pickled data - Python .npy I/O

问题描述

我尝试使用np.save()将数据帧和矩阵另存为.npy文件，然后使用np.load()读取它们，但出现以下错误:

I am trying to save a dataframe and a matrix as .npy files with np.save() and then read them using np.load() but I get the following error:

  File "/Users/sofiafarina/opt/anaconda3/lib/python3.7/site-packages/numpy/lib/npyio.py", line 457, in load
    raise ValueError("Cannot load file containing pickled data "

ValueError: Cannot load file containing pickled data when allow_pickle=False

即使我写allow_pickle = True，我也会收到一个错误:

Even if I write allow_pickle=True I get an error:

  File "/Users/sofiafarina/opt/anaconda3/lib/python3.7/site-packages/numpy/lib/npyio.py", line 463, in load
    "Failed to interpret file %s as a pickle" % repr(file))

OSError: Failed to interpret file 'finaldf_p_85_12.npy' as a pickle

那么我该如何从python脚本中保存df，然后将其加载到另一个脚本中呢?我应该使用其他功能吗?谢谢！

So how could I save a df from a python script and then load it in another one? Should I use other functions? Thank you!

推荐答案

我使用下面的语法加载了 .npy 文件，该文件起作用了.

I used the syntax below to load the .npy file and it worked.

np.load("finaldf_p_85_12.npy",allow_pickle=True)

我认为您需要添加 allow_pickle = True 参数.

I think you need to add allow_pickle=True parameter.
