you be funniny an ipynb file form a subdirectory of your gdrive , but when you open() a data file in the same folder you might get "file not found".
Although you maybe be running an ipynb file from a subdirectory of your gdrive, an open() call will read from the root of your gdrive. You might get "file not found".

Google Collaboratory Oddities

Google colaboratory is like a hosted jupyter labs that has gdrive integrated. This can be handy but there are some adjustments required.

As part of the setup process you will need to "enable the app". I did this by right clicking in gdrive on an ipynb file and choosing "add app".

in the app search , search "Colaboratory"

https://colab.research.google.com/

Also you may need to give Colaboratory access to you gdrive.

<FIXME : how ? >

You can "mount" your gdrive in you ipynb files like this:

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

Although you maybe be running an ipynb file from a subdirectory of your gdrive, an open() call will read from the root of your gdrive. You might get "file not found".

To fix this change your working directory:

not like this:

!cd gdrive/path/to/file

but like thisL:

%cd gdrive/path/to/file
#Z and see the change with 
!pwd
