问题：

with open(filename, 'rb') as f:

----> 9     datadict = pickle.load(f)      10     X = datadict['data']      11     Y = datadict['labels']

UnicodeDecodeError: 'ascii' codec can't decode byte 0x8b in position 6: ordinal not in range(128)

 

解决办法：

with open(filename, 'rb') as f:

    datadict = pickle.load(f,encoding='iso-8859-1')     X = datadict['data']     Y = datadict['labels']

 

具体原因是为毛，后面再研究。先记录一下该问题。
