%run rl_base.py

I run this giving error saying rl_base.py file not found. I have uploaded the same to gdrive in colab and from the same folder I am running my .ipynb file, containing the above code

回答1:

If you have the test.py file in the corresponding folder in drive as in the below attached image, then the command which you use to run the test.py file is as mentioned below,

!python gdrive/My\ Drive/Colab\ Notebooks/object_detection_demo-master/test.py

Additional Info:

If you jusst want to run !python test.py then you should change directory, by the following command before it,

%cd gdrive/My\ Drive/Colab\ Notebooks/object_detection_demo-master/

When you run your notebook from Google drive, an instance is created only for the notebook. To make the other files in your Google drive folder available you can mount your Google drive with:

from google.colab import drive
drive.mount('/content/gdrive')

Then copy the file you need into the instance with:

!cp gdrive/My\ Drive/path/to/my/file.py .

And run your script:

!python file.py

回答3:

You should not upload to gdrive. You should upload it to Colab instead, by calling

from google.colab import files
files.upload()

It seems necessary to put the .py file's name in ""
!python "file.py"
