UnicodeDecodeError Python/Django应用程序

Question

我得到了这个错误

在我的Django应用程序上，已经在Apache上了，我无法找出问题出在哪里，因为我正在处理编码（至少我认为是这样的…）

我的代码（按顺序）：

^{pr2}$

TextMining类的功能：

class TextMining(object):
    def __init__(self, file_path, keywords):
        self._file_path = file_path
        self._keywords = keywords
        self._sentences = list()
        self._keyword_sentences = dict()

        self.lower_keywords()
        self.separete_file_sentences()
...
    def separete_file_sentences(self):
        with open(self._file_path, "r", encoding='utf-8') as text_file:
            file_text = text_file.read()
            sentences = nltk.tokenize.sent_tokenize(file_text)

            for i in range(len(sentences)):
                if(len(sentences[i]) > 0):
                    self._sentences.append(sentences[i])

我已经处理了好几天了，尝试了很多方法，但都没用。。在

在网址.py（文本挖掘应用程序）

urlpatterns = [
        url(r'^$', views.index, name='index'),
        url(r'^select_text', views.select_text, name = 'select_text'),
        url(r'^edit_text', views.edit_text, name = 'edit_text'),
        url(r'^generate_aiml', views.generate_aiml, name = 'generate_aiml'),
]

在网址.py（文本管理项目）

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^', include('textMining.urls')),
] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

if settings.DEBUG is True:
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
