如何解决?
在其他一些基于python的静态博客应用中，中文帖子可以成功发布。
比如这个应用:http://github.com/vrypan/bucket3。在我的网站http://bc3.brite.biz/，中文帖子可以成功发布。
最后我明白了:
as3:/usr/local/lib/python2.7/site-packages# cat sitecustomize.py
# encoding=utf8
import sys
reload(sys)
sys.setdefaultencoding('utf8')
让我查一下:
as3:~/ngokevin-site# python
Python 2.7.6 (default, Dec 6 2013, 14:49:02)
[GCC 4.4.5] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> reload(sys)
<module 'sys' (built-in)>
>>> sys.getdefaultencoding()
'utf8'
>>>
上面显示了python的默认编码是utf8。那么错误就不再存在了。
"UnicodeDecodeError: 'ascii' codec can't decode byte"
错误原因:input_string必须是unicode，但给出了str
"TypeError: Decoding Unicode is not supported"
此错误的原因:试图将unicode input_string转换为unicode
因此，首先检查你的input_string是否为str，并在必要时转换为unicode:
if isinstance(input_string, str):
input_string = unicode(input_string, 'utf-8')
其次，上面只是改变了类型，但没有删除非ascii字符。如果你想删除非ascii字符:
if isinstance(input_string, str):
input_string = input_string.decode('ascii', 'ignore').encode('ascii') #note: this removes the character and encodes back to string.
elif isinstance(input_string, unicode):
input_string = input_string.encode('ascii', 'ignore')
这是我的解决方案，只需添加编码。
用open(file, encoding='utf8')作为f
因为读取glove文件需要很长时间，所以我建议将glove文件转换为numpy文件。当你读取嵌入权重时，它将节省你的时间。
import numpy as np
from tqdm import tqdm
def load_glove(file):
"""Loads GloVe vectors in numpy array.
Args:
file (str): a path to a glove file.
Return:
dict: a dict of numpy arrays.
"""
embeddings_index = {}
with open(file, encoding='utf8') as f:
for i, line in tqdm(enumerate(f)):
values = line.split()
word = ''.join(values[:-300])
coefs = np.asarray(values[-300:], dtype='float32')
embeddings_index[word] = coefs
return embeddings_index
# EMBEDDING_PATH = '../embedding_weights/glove.840B.300d.txt'
EMBEDDING_PATH = 'glove.840B.300d.txt'
embeddings = load_glove(EMBEDDING_PATH)
np.save('glove_embeddings.npy', embeddings)
