There is definitely something from anaconda messing this up too…

AttributeError: module ‘serial’ has no attribute ‘Serial’
This error output line from my previous message seems to hold the key to the issue.
ImportError: cannot import name ‘Serial’ from ‘serial’ (C:\Users\custard\anaconda3\lib\site-packages\serial_init_.py)
it’s something about the python installation me thinks.
i think anaconda making trouble,
if you are able to launch jupyter from chipwhisperer then remove anaconda and try it again. install jypyter manually if need
before this try this command
import chipwhisperer as cw
from serial import Serial
cw.program_sam_firmware(hardware_type='cwlite')

Not super familiar with Anaconda, but try running the following in a CMD window that has access to the python you’re using. You can check where the python is via python -c 'import sys; print(sys.executable)':
python -m pip uninstall pyserial
python -m pip uninstall serial
python -m pip install pyserial

It looks like you’re using the Python install that comes with the CW installer. Do you want to use that one, or continue with the Anaconda install?
If you want to use the CW python, try grabbing the packages it says you’re missing:
python -m pip install configobj
python -m pip install ECpy
python -m pip install fastdtw
python -m pip install pyusb
I’d recommend starting Jupyter via C:\Users\custard\ChipWhisperer5_64\ChipWhisperer

Hi Alex,
I would really like to install Anaconda again, and use that python and jupyter install. I don’t have a clear understanding of whether that is possible, and if it is, I am not sure why it didn’t “just work” when I installed CW5.5.2 on my system (Anaconda was already installed).
Currently, Anaconda is not installed because I removed the anaconda installation to help try and resolve the issue with CW picking up that python as it was in the %PATH I guess.
This appears to be the cause of all my initial issues, looking back to the 3rd post in this discussion.
If you think it can work with Anaconda installed first, I’m very happy to start over with that and follow your directions.
cheers,
Paul
Hi Paul,
We should be able to get CW working via Anaconda, though it seems to be a bit finicky. Normally we just recommend the installer since installing Python, getting the compilers, figuring out path stuff, etc can be a bit rough on Windows. If you don’t have it yet, you’ll want to grab git bash: Git - Downloads. All the defaults should work here, with the exception Enable experimental support for pseudo consoles (on the last install page), which you’ll want to have checked.
Once you’ve got that installed, install Anaconda. Make sure you install for all users and check the option to add it to your system path, as not doing this seems to break some of the packages that come with Anaconda when we run Python through Git Bash. Open a Git Bash terminal and verify that python you’ve got access to is the one from Anaconda: python -c "import sys; print(sys.executable)". You’ll need to restart Git bash to have the new path apply.
Next, add the following paths from the ChipWhisperer install to your System variables Path:
\path\to\ChipWhisperer5_64\cw\home\portable\armgcc\gcc-arm-none-eabi-10-2020-q4-major\bin\path\to\ChipWhisperer5_64\cw\home\portable\avrgcc\avr-gcc-10.1.0-x64-windows\bin
Next, in Git Bash, verify that you have access to compilers by running the following:: make --version, arm-none-eabi-gcc --version, and arm-gcc --version.
Navigate to \path\to\ChipWhisperer5_64\cw\home\portable\chipwhisperer and run the following commands to update and install ChipWhisperer:
git config --global --add safe.directory $(pwd)
git config --global --add safe.directory $(pwd)/jupyter
git fetch --all
git reset HEAD --hard
git submodule update --init jupyter
python setup.py develop --user
python -m pip install -r jupyter/requirements.txt --user
Once this is done, you should be able to run python -m jupyter notebook and have Jupyter open. The steps above also updated ChipWhisperer for you, so if you need to reflash your device, you should have access to cw.program_sam_firmware(). Your original issue with this part is because this function isn’t available on CW 5.5.2 (I’ve updated Updating Firmware — ChipWhisperer 5.6.1 documentation to make this more clear).
Let me know if you run into any issues with these steps.
Alex
Hi Alex,
Thank you for that detailed reply. I am ready to give that a try after work. However, given you also found that using the Anaconda install is finicky, I would be perfectly happy using CW with the resources/binaries which it ships with, so long as I can still have Anaconda installed on my system for other development.
I had initially presumed this was the intended use case, but as per my previous messages, the Chipwhisperer shortcut failed to launch anything, and the captured error mentions anaconda install stealing the focus. If this could be fixed more easily/reliably, then I am totally on board for that.
cheers,
Paul
Hi Paul,
Yeah, ChipWhisperer should be separate from other Python instances on your machine.
Just to check, have you tried running the ChipWhisperer shortcut that is in the actual install directory for ChipWhisperer? That one should definitely work on 5.5.2. If it doesn’t, can you try going to ChipWhisperer5_64\cw and running mintty.bat? From there, run jupyter notebook and let me know if you get any errors.
Alex
Hello Alex, sorry it’s been a few days since I could give this more time. I followed the exact steps in your last msg. Before I did anything though, I completely removed anaconda install from my PC and also the CW install. I totally removed the folders these were in. Then I installed Chipwhisperer.v5.5.2.Setup.64-bit.exe (from github). Then I tried the CW shortcut on the desktop, which didn’t start anything. The brief message that flashed up said
C:\Users\xxx\CHIPW~1\cw\home\portable\WPy64-3771\python-3.7.7.7.amd64\python.exe: No module named jupyter.main; ‘jupyter’ is a package and cannot be directly executed
So I then installed anaconda and tried again. Same result. So then I pressed on with your instructions. The Shortcut in the install folder gave the same result. Then I ran the mintty.bat (using a windows command shell) which opened a linux sort of shell. I ran “jupyter notebook” and got the following result. See attached image.
Please let me know what I can try next, I am out of ideas.
Cheers,
Paul
Hi Paul,
When you ran through the installer, you should’ve seen a small bash window pop up. Did you let that run to completion? Unfortunately, that version of the installer runs that part asynchronously to the rest of the installer, so it’s possible to close the installer before it’s fully finished.
Anyway, can you try navigating to cw/home/portable/chipwhisperer and running python -m pip install -r jupyter/requirements.txt? Once that’s done, try running jupyter notebook again. If it still doesn’t work, try python -m jupyter notebook.
Alex
