这是我的代码：

import pickle

# Load model weights and Metadata
weightFile = open('vgg16.pkl','rb')
d = pickle.load(weightFile)

当我运行它时,我得到了输出

"C:\Program Files\Python35\python.exe" C:/work/lasagne/tutorial/lasagne-tutorial2.py
Traceback (most recent call last):
  File "C:/work/lasagne/tutorial/lasagne-tutorial2.py",line 5,in <module>
    d = pickle.load(weightFile)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xbc in position 1: ordinal not in range(128)

Process finished with exit code 1

这个错误信息是什么意思？它说有一个字节,acsii编解码器无法解码,但不是pkl文件应该是二进制(因此不包含ascii字符)？

我在加载文件时做错了什么？我该怎么做才能解决错误？
