加载npy数组时，无法将文件％s解释为pickle

Question

Hi I am a new user to python and want to import a saved npy array. When attempting to load the npy array, I get the following error message. Thanks in advance!

import numpy as np

A = np.load('C:/Final Runs/lineTank.npy')

I receive these errors:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python27\lib\site-packages\numpy\lib\npyio.py", line 384, in load
    "Failed to interpret file %s as a pickle" % repr(file))
IOError: Failed to interpret file 'C:/Final Runs/lineTank.npy' as a pickle

Answer 1

Thanks for the help guys. I realized @Joe Kington was right. The file was creating using the traditional python write to a file as opposed to numpy. This is what I had used (which didn't work):

f = open(Filename, "w")
try:
    f.write(a)
finally:
    f.close()

as opposed to using numpy's save, which works:

import numpy as np
np.save(Filename, a)
a = np.load(Filename)

You might need to load the file into a string first, then numpy.load() the string.

Something like :

with f as file.open(filename):
  foo = f.readlines()
bar = numpy.load(foo)
