Please see this link to learn about grader metadata.
If grader metadata is missing, refresh your workspace and try again.
See Refresh your Lab Workspace section here
If you’ve already done this, contact coursera help

Should you be unsure if this is a metadata issue or your solution is wrong, click my name and message your notebook as an attachment.

@Siddartha_Marella

There’s no grader metadata in the notebook for the cell containing create_train_val_dirs

{
  "cellView": "code",
  "executionInfo": {
    "elapsed": 1163,
    "status": "ok",
    "timestamp": 1659743493520,
    "user": {
      "displayName": "Siddartha Marella",
      "userId": "<Removed manually>"
    },
    "user_tz": 240
  },
  "id": "F-QkLjxpmyK2",
  "trusted": false
}

Please read up on metadata in my previous post and do the next steps.

For course2 : Convolution neural networks in TensorFlow, the assignment code is hosted on GitHub and I am doing an assignment using Colab, so I am unable to access metadata, What to do in this situation to solve this problem?

Thank you

Here are the steps:

  1. On google colab, File > Download > Download .ipynb and save it on your disk at say, /home/myuser/notebooks/mynotebook.ipynb
  2. Launch the notebook on your local system using
    $ jupyter /home/myuser/notebooks/mynotebook.ipynb
  3. Follow these instructions.
