无法在google colab中上传本地文件

Question

I am trying to upload a word2vec file in Google Colaboratory from local system and use it further in the in code.

This is the code that I used.

from google.colab import files
uploaded = files.upload()

Everytime I execute it, it is showing the following error.

Upload widget is only available when the cell has been executed in the current browser session. Please rerun this cell to enable

 MessageError  Traceback (most recent call last)
<ipython-input-1-292f82be1b7a> in <module>()  

      1 from google.colab import files
      2 
----> 3 uploaded = files.upload()`
      4 
      5 for fn in uploaded.keys():

/usr/local/lib/python3.6/dist-packages/google/colab/files.py in upload() 

     59   result = output.eval_js(
     60       'google.colab._files._uploadFiles("{input_id}", "{output_id}")'.format(
---> 61           input_id=input_id, output_id=output_id))
     62   files = collections.defaultdict(six.binary_type)
     63 

/usr/local/lib/python3.6/dist-packages/google/colab/output/_js.py in 
eval_js(script, ignore_result)

     37   if ignore_result:
     38     return
---> 39   return _message.read_reply_from_input(request_id)
     40 
     41 

/usr/local/lib/python3.6/dist-packages/google/colab/_message.py in 
read_reply_from_input(message_id, timeout_sec)

     84         reply.get('colab_msg_id') == message_id):
     85       if 'error' in reply:
---> 86         raise MessageError(reply['error'])
     87       return reply.get('data', None)
     88 

MessageError: TypeError: google.colab._files is undefined

Why is this happening? What should I do?

Answer 1

This issue is currently being investigated for Firefox at: https://github.com/googlecolab/colabtools/issues/51 .

As a temporary workaround is there recommended to upload files by Chrome.

Answer 2

Switching off Enhanced Protection for the site in Firefox, which is accessible via the little "security shield" to the left of the URL, did the trick perfectly for me...

Answer 3

Well for me, I first tried to factory reset the runtime but it didn't work

Then i just restarted the runtime and refreshed the page, it then worked for me.

Answer 5

For me, this happened when my computer was simply overloaded. It was unable to manage colab and my other tabs being open. Closing colab and the other tabs in the taskmanager before trying again solved the problem for me.
