Using CWTVLA from Jupyter

[CsquaredPhD]

I am trying to execute the CWTVLA notebook on my CW305.

However, I’m not able to get CWTVLA installed and imported in this environment. I’m using Release 5.5 installed on Windows 10.

I tried the following:

import sys
!{sys.executable} -m pip install cwtvla

and

%pip install cwtvla

In both cases, pip list shows cwtvla 0.1.0 installed. However, even after restarting kernel and Jupyter server, import cwtvla gives ModuleNotFoundError: No module named 'cwtvla'.

What is the proper procedure to get CWTVLA working in Jupyter?

Thanks,
Chris

Thanks, Alex. Just wondering if you had any update on this issue?

I haven’t figured out the cause yet, but if you install from github directly by downloading https://github.com/newaetech/chipwhisperer-tvla and running python setup.py install in the downloaded directory it should work as a quick fix.

I found at least one of the issues:

SCA230 -- Issue, root cause, workaround, and requested fix

While going through SCA203, I kept having trouble with the jupyter notebooks. Eventually, I was able to find a root-cause and workaround. This post is to document for others who might hit this, and to request a fix by maintainer of the cwtvla module. How to determine if you are affected Run pip check – does it list any version conflicts, especially about numpy and chipwhisperer? Background the chipwhisperer 6.0.0 module requires numpy <=1.26.4. the cwtvla 0.1.3 module requires numpy, but d…

The recommendation to install the cwtvla module directly may break your virtual environment. Details in linked post.
