Question

我正在尝试在IBM Cloud / Bluemix上运行带有某些文本分析功能（使用TextBlob）的python flask应用程序。通过cf push命令部署该应用程序后，出现以下错误（请参见下文）。站点，当用户尝试使用需要用户在其系统上没有的数据集或模型的功能时，将引发此异常。

error:
Error while running the app:
textblob.exceptions.MissingCorpusError
MissingCorpusError: 
Looks like you are missing some required data for this feature.

To download the necessary data, simply run

python -m textblob.download_corpora
or use the NLTK downloader to download the missing data: 
http://nltk.org/data.html
If this doesn't fix the problem, file an issue at 
https://github.com/sloria/TextBlob/issues.

现在我的问题是我在我的require.txt文件中添加了Flask，Textblob和NLTK，如下所示。没有运行上面提到的命令，还有其他方法可以使这项工作吗？注意：此应用程序可在本地系统上完美运行。

requirement.txt content:
Flask==0.12.2
cloudant==2.4.0
textblob==0.15.1
nltk==3.3

这是错误/警告，当我通过push命令部署应用程序时得到

        -----> Downloading NLTK corpora...
!     nltk.txt not found, not downloading any corpora

Henrik询问的编辑：当我运行以下命令python -m textblob.download_corpora时，正在我的系统上下载corporas。我在nltk.txt文件中提到了相同的列表

`[nltk_data] Downloading package brown to

 Finished.

这就是我的nltk.txt的样子

brown wordnet
averaged_perceptron_tagger
brown
sentence_polarity
sentiwordnet
subjectivity
words
punkt
maxent_treebank_pos_tagger
movie_reviews
conll2000

我在nltk.txt中添加了其他语料库，如下所示，希望没问题

 sentence_polarity
 sentiwordnet
 subjectivity
 words

Answer 1

似乎您部署的应用程序的根目录中没有nltk.txt。 The Cloud Foundry Python buildpacks have built-in support for NLTK。文本文件包含有关在部署过程中需要安装哪个语料库的信息。

nltk.txt的内容示例：

wordnet averaged_perceptron_tagger brown sentence_polarity

确保它是一行，没有重复，也没有奇怪的字符...

IBM Cloud / bluemix上的Python Flask应用程序带有Textblob库抛出异常-textblob.exceptions.MissingCorpusError
