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。


当前回答

"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')

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。

这招对我很管用:

    file = open('docs/my_messy_doc.pdf', 'rb')

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)

我在Python2.7中遇到了这个错误。我在尝试运行许多python程序时遇到了这种情况,但我设法用这个简单的脚本重现了它:

#!/usr/bin/env python

import subprocess
import sys

result = subprocess.Popen([u'svn', u'info'])
if not callable(getattr(result, "__enter__", None)) and not callable(getattr(result, "__exit__", None)):
    print("foo")
print("bar")

在成功的情况下,它应该打印出'foo'和'bar',如果你不在svn文件夹中,可能会有一个错误消息。

在失败时,它应该打印'UnicodeDecodeError: 'ascii' codec不能解码字节0xc4在位置39:序号不在范围(128)'。

在尝试重新生成区域设置和这个问题中发布的许多其他解决方案后,我了解到发生了错误,因为我的PATH环境变量中编码了一个特殊字符(ĺ)。在` ~/中固定PATH后。Bashrc ',然后退出我的会话并再次进入,(显然是在查找'~/。Bashrc’没有起作用),问题就消失了。

Encode将unicode对象转换为字符串对象。我认为你正在尝试编码一个字符串对象。首先将结果转换为unicode对象,然后将该unicode对象编码为'utf-8'。 例如

    result = yourFunction()
    result.decode().encode('utf-8')
