Я пытаюсь создать wordcloud с python, но обнаружил ошибку.
# This is the uploader widget
def _upload():
_upload_widget = fileupload.FileUploadWidget()
def _cb(change):
global file_contents
decoded = io.StringIO(change['owner'].data.decode('utf-8'))
filename = change['owner'].filename
print('Uploaded `{}` ({:.2f} kB)'.format(
filename, len(decoded.read()) / 2 **10))
file_contents = decoded.getvalue()
_upload_widget.observe(_cb, names='data')
display(_upload_widget)
_upload()

Здравствуйте, я получаю сообщение об ошибке после стольких исследований, мне не удалось найти решение, поэтому я решил разместить здесь. Это было похоже на то, как будто я приложил столько усилий, чтобы написать это, но вы знаете, что ошибка сохраняет все.
NameError Traceback (most recent call last)
<ipython-input-8-fd0f708f372c> in <module>

----> 3 myimage = calculate_frequencies(file_contents)
4 plt.imshow(myimage, interpolation = 'nearest')
5 plt.axis('off')
NameError: name 'file_contents' is not defined
Пожалуйста, помогите мне в решении этой проблемы. Мне это очень нужно!
