Zero Division Error in PyRPL GUI initial setup

[GeorgeGuannan]

Hi, I am trying to setup the PyRPL GUI, followed by the instruction here: https://pyrpl.readthedocs.io/en/latest/gui.html#start-gui-label Specifically, in Section 2.2 Starting the GUI . Unfortunately, a Zero Division Error occurs when I am executing the PyRPL.exe file or runing the python script, following are the messages I get. Thank you for your help!

Following is some background information that might be useful.

1. Preparation of Red Pitaya SD card:

I prepared the SD card using the OS image version 2.00-30. However, I noticed that the PyRPL documentation refers to using OS image version 0.92.

2. Installation and Anaconda Environment Setup

I installed the .exe file and built the conda environment using the following .yml file I made for packages, which specifies their corresponding versions. name: pyrpl_env_spd dependencies:

• python=3.6
• numpy
• scipy
• paramiko
• pandas
• nose
• pip
• pyqt
• qtpy
• pyqtgraph
• pyyaml
• spyder
• git

Additionally, I established an SSH connection to the Red Pitaya device.

3. The config file "example_filename"

• The MAC address of my Red Pitaya is: 00:26"32:F0:C0:BA
• The Ethernet connection status with my PC is stable, and I can access the Red Pitaya's GUI by opening its IP address in the browser without any issues.

I really appreciate any help!

This issue is fixed, thanks to this post: #505. The original OS in my SD card is RP 2.00-30, which is very new. I downgraded it to 1.04-18, and it seems working.
