Running Pronterface on Aarch64 and Trying Other Tools in the Suite

[set_]

Hello,

Traceback (most recent call last):
  File "/usr/bin/pronterface", line 30, in <module>
    from printrun.pronterface import PronterApp
  File "/usr/lib/python3/dist-packages/printrun/pronterface.py", line 32, in <module>

    from printrun.plugins import PRINTCORE_HANDLER
ImportError: cannot import name 'PRINTCORE_HANDLER' from 'printrun.plugins' (unknown location)

I have put the exported files in .bashrc and then sourced the .bashrc file to run my commands. This has not worked from my ~/$HOME directory.

This is fine. I can use python3 /usr/bin/pronterface to handle the issue. The above set of displaced imports in Python3 persist.

Has anyone come to get this error and found a workaround yet?

P.S. Oh and should printrun work w/ aarch64?

Hi @silver2row, could you please share:

1. your OS
2. your version of Pronterface
3. and how you installed Pronterface?

I don't really understand the process you describe above for installation. Did you try installing via PyPI?

P.S. Oh and should printrun work w/ aarch64?

Absolutely, it should work with no issues on ARM64.

1. Debian Bookworm
2. the Debian Bookworm install via sudo apt install printrun
3. sudo apt install printrun

I have not tried w/ PyPI b/c of Debian Bookworm not playing nice w/ python3 -m pip install printrun or any pip3 installs.

2. the Debian Bookworm install via sudo apt install printrun

That's weird, that should work out of the box. Am I right in thinking that you can't just run pronterface in a terminal and get it to run? You are having to run it like python3 /usr/bin/pronterface? If so, that sounds like you PATH is not properly configured. Anyway, you seem to be missing the plugins directory for Printrun. The following command should show this output (or similar). A missing plugins directory there means the apt install printrun failed to install all files somehow?

$ ls /usr/lib/python3/dist-packages/printrun/plugins
__init__.py  __pycache__  sample.py

I have not tried w/ PyPI b/c of Debian Bookworm not playing nice w/ python3 -m pip install printrun or any pip3 installs.

Well done. That's why we recommend using Python virtual environments instead of the "system's" pip install.

oh...right. I cannot run pronterface and have it run. I am on a vncserver w/ vnc viewer while running the pronterface command. And yes, I have to run the command python3 /usr/bin/pronterface to have it error out but...

1. I see there is an X11 in /usr/bin/ and the repetition of files in /usr/bin/ are there exactly like /usr/bin/X11. I am just saying I have pronterface and pronsole in both /usr/bin/ and /usr/bin/X11.

I tried w/ pronsole and ended up w/ the same error.

I will get back to you on the ls command so that I can give some more insight on this issue.

And okay about the virtual env. I will test it that way too. Thank you for dealing w/ me so far.

It seems I am not in control of my own system. Hmm. Let me try to add permissions and some rules.

This is the printrun versioning I currently have on my TDA4VM:

printrun is already the newest version (2.0.0~rc8-2).

Hello...I just did not want to use sudo or get into a root account. I am forced to do so and this solves the issue. I am sorry to give you trouble w/ these bunch of errors.
