It depends from where you start the script. If you start it from the top level directory of both folders then it should work.
toplevel/ package/ init.py code.py notebooks/ testing.ipynb
For instance, with the above directory structure, launch testing.ipynb
with toplevel
being your working directory.

QUESTION
Is there a way to do something like a rc file with Altair?
I currently create an Altair theme at the beginning of my notebooks (to set up plot size and font size, etc.) and then register and enable it.
...ANSWER
Answered 2021-Jun-11 at 17:30I don't think there is a file that Altair reads at startup. If you want to avoid copy pasting the same theme code into each notebook, you can create a Python package with your theme. There are several examples of how to set this up on GitHub e.g. this la times theme.

...ANSWER
Answered 2021-Jun-10 at 13:41This is the correct answer. Numpy like all computers calculating in binary has a small margin of error. You can circumvent this by rounding to 14 digits (for 32-bit floating point numbers):
QUESTION
I tried to disable notebooks.googleapis.com with the command line and the developer interface but it is failing. From the command line when I try
...ANSWER
Answered 2021-Jun-10 at 05:22Notebooks are based on Compute Instances. If you activate Notebooks API and create a new Notebook from Notebooks UI, you will see the corresponding VM in both Notebooks UI and Compute Engine page. If you want to disable Notebooks API you need to:
- Backup Noteboks information
- Delete Notebooks from Notebooks UI page. This will delete Notebooks records and VMs
- Deactivate Notebooks API
- Go to Notebooks UI and create back the Notebooks (this will use Compute Engine API instead) We use Compute Engine API when Notebooks API is not enabled. This is currently discouraged but you have this option. (You will miss features such as auto-upgrade, health endpoint, instance monitoring)
Curious: Why you want to Disable Notebooks API?

including 286 images with the shape of (286, 16, 16, 3)
. Each image contains 3 bands with varying pixel values with float32 data types. The maximum value of pixel value in each band can be more than 255. Is it possible to normalize this numpy.ndarray between [0-1]?
code for reading the images:
...ANSWER
Answered 2021-Jun-09 at 09:21If you want the range of values of every image to be between 0 and 255, you could loop over the images, calculate min and max of the original image and squeeze them, so the minimum is 0 and the maximum is 255.
