It's to do with uploading of stop words module. As a work around import stopwords library with in the function itself. please see the similar issue linked below. I had same the issue and this work around fixed the problem.

    def stopwords_delete(word_list):
        from nltk.corpus import stopwords
        filtered_words=[]
        print word_list
