无法加载在Google Colaboratory中创建的模型

Question

我已经在Google Colab中使用Keras训练了CNN，但是下载模型后，无法将hdf5文件加载到本地系统（Windows）中。

我以前做过，从来没有任何问题。这是我得到的错误。

Traceback (most recent call last):
  File "D:/Work/binary-face-recognition/predict-test.py", line 27, in <module>
    model = load_model('model.hdf5')
  File "C:\Users\PARTHA.N\AppData\Local\Continuum\anaconda3\envs\face\lib\site-packages\keras\engine\saving.py", line 417, in load_model
    f = h5dict(filepath, 'r')
  File "C:\Users\PARTHA.N\AppData\Local\Continuum\anaconda3\envs\face\lib\site-packages\keras\utils\io_utils.py", line 186, in __init__
    self.data = h5py.File(path, mode=mode)
  File "C:\Users\PARTHA.N\AppData\Local\Continuum\anaconda3\envs\face\lib\site-packages\h5py\_hl\files.py", line 312, in __init__
    fid = make_fid(name, mode, userblock_size, fapl, swmr=swmr)
  File "C:\Users\PARTHA.N\AppData\Local\Continuum\anaconda3\envs\face\lib\site-packages\h5py\_hl\files.py", line 142, in make_fid
    fid = h5f.open(name, flags, fapl=fapl)
  File "h5py\_objects.pyx", line 54, in h5py._objects.with_phil.wrapper
  File "h5py\_objects.pyx", line 55, in h5py._objects.with_phil.wrapper

OSError: Unable to open file (truncated file: eof = 38486016, sblock->base_addr = 0, stored_eof = 72708080)

要加载模型，我正在进行基本的load_model调用

from keras.models import load_model
model = load_model('model.hdf5')

要使用以下代码段从Google Colab保存并下载模型，请使用以下代码段。

# save model
model.save('model.hdf5')

# download model
from google.colab import files
files.download('model.hdf5')

下载文件后，在files.download()行的Google colb中出现以下错误。

我确实遇到了同样的问题，不同的是我从文件管理器中下载了文件，并且同样工作正常。

单击屏幕左上角位于colab标志下方的小箭头，类似于

然后，您需要单击文件并导航至所需的文件，右键单击并下载所需的文件。这对我来说效果更好，并且没有连接错误，在files.download方法中就是这种情况

Answer 2

好像互联网连接出现问题。我切换到另一个WiFi，它工作正常。

这个问题现在听起来很愚蠢，但请保留下来，并回答这个问题，希望对遇到相同问题的人有所帮助。
