UNSOLVED: Python Wrapper Error DEFAULT_RESOLUTION
UNSOLVED: Python Wrapper Error DEFAULT_RESOLUTION
Hello,
PicoSDK's Python Wrapper is throwing an "AttributeError" message when trying to run the test code, found here: https://github.com/picotech/picosdk-pyt ... -this-code
Error:
AttributeError: 'Ps6000alib' object has no attribute 'DEFAULT_RESOLUTION'
Hardware:
I'm connecting a PicoScope 6000 6824E to my Windows 10 (64-bit) PC, via USB.
Driver:
PicoSDK (64-bit), Mar/10/2022. Filename PicoSDK_64_10.7.22.241.exe.
Additional:
I'm running Python 3.9.7 (fellow troubleshooters, to determine your version, type `python --version` in bash). It is 64-bit. My Windows OS, driver and python "bitness" all match. I am running on conda.
Steps to Error:
I've walked many times through the Python Wrapper setup process documented here: https://github.com/picotech/picosdk-pyt ... ng-started
Download Driver
1. Installed PicoSDK 64-bit. Notably, many of the Pico driver downloads for different models (4000, 5000, 6000, etc) all link to the same SDK download driver.
Setup Wrapper
2. There are two possible paths to install the python wrapper. You can `pip install picosdk`. However, when examining the repo on PyPi (https://pypi.org/project/picosdk/), it appears this was last updated December 2020. As such, it seems preferable to install from the GitHub repo (https://github.com/picotech/picosdk-python-wrappers). At the time of posting, this repo was last updated July 22 2022. The last commit seems unrelated to this issue.
First, clone this repo to local. I then open Git Bash inside this local directory, and run `python setup.py install`. Then, install dependencies using `pip install -r requirements.txt`.
To confirm the package has installed, run command `pip list` and find `PicoSDK` in the list, version 1.0.
Run Code
3. Finally, launch python and run the code to determine drivers, found here:
https://github.com/picotech/picosdk-pyt ... -this-code
Error
This produces error:
Troubleshooting attempts:
Over the course of several days, I've walked through the above installation steps several times. I've also tried a few creative solutions such as:
1. Edited `test/test_helpers.py's`, by uncommenting line 37 (# 'ps6000').
2. Added ps6000a into that document where it seemed relevant.
3. Followed this install methodology on 2 PCs, one running Windows 10, another Windows 11.
4. Followed all forum posts and solutions (replug USB, editing discover.py). The following solution did not resolve the issue. topic41789.html?&p=147602&hilit=DEFAULT ... ON#p147602
5. Followed `pip install picosdk`
6. Installed into a new conda env, and installed into base env
7. Run the code with Pico 6 software running, and with it closed, restarting python each time.
8. Last but not least, I have restarted both the PC and PicoScope.
Preemptive Thank You for any ideas,

Do any of the individual examples for the PicoScope 6824E work?
