AttributeError on Displaying Traces with ChipWhisperer-Lite on Ubuntu

[abolfazlsajadi]

Hello ChipWhisperer Team,

I've encountered an issue with the ChipWhisperer-Lite on my Ubuntu system. I followed the installation guide closely using pyenv, as outlined in the ChipWhisperer Installation Guide for Ubuntu, and didn't run into any errors or warnings during the process.

Issue Description: The problem arises when I attempt to display traces using the command cw.plot(wave). Each time I do this, I encounter the following error: ` AttributeError Traceback (most recent call last) Cell In[9], line 1 ----> 1 cw.plot(wave)

Troubleshooting Steps Taken:

• I've tried reinstalling the software on another system to rule out any system-specific issues, but the same error persists.

I am seeking guidance or suggestions on potential solutions to this problem. Any help would be greatly appreciated, as this issue is hindering my progress.

Thank you for your time and assistance.

Hi,

Can you try updating the jupyter requirements.txt packages and seeing if that fixes your issue:

cd jupyter
pip install -r requirements.txt --upgrade

[abolfazlsajadi]

Unfortunately, updating the requirements.txt for Jupyter didn't resolve the issue. I encountered a ModuleNotFoundError related to 'jupyter_server.contents'. To fix this, I upgrade the notebook version to 6.5.6. While this adjustment resolved the module error, I'm still experiencing problems with cw.plot(wave) not functioning. However, I'm able to use plt for checking Waves.

Can you try grabbing the latest jupyter commit and running pip install --upgrade --force-reinstall -r requirements.txt instead?
