Multiple issues with dependencies

[a6a3uh]

It seems like dependencies listed in requirements.txt are not enough. At least on Mac OSX. And probably on any clean system.

What I did to make some progress (I used conda) is as follows:

conda create --name kucher2 python=3.6 --no-default-packages

source activate kucher2

conda install pyqt

conda install numpy

conda install pytest

conda install pyserial

pip install quamash

conda install cython

pip install construct

And finally stuck with popcop missing or not working (producing Assert on import) if just plain copied with issue described here.

Fixing that by just commenting line causing assertion I get to next issue with missing import in popcop.

Yes, requirements.txt requires updating; I'm going to keep this open for now.

I see quamash is a submodule dependency so could not be installed separately. Or could be removed from submodules. The same is for construct. It's submodule version is compatible with application while the latest one is not.

[a6a3uh]

Btw. While app is running in python 3.6.6. With python 3.7.0 it gives

Traceback (most recent call last):
File "./zubax-kucher", line 22, in

File "... kucher/kucher/main.py", line 45, in main

The stack trace you posted is incomplete.

[a6a3uh]

Sorry. Updated the message with full stack trace.
Editor removes indentation. Actually arrow is pointing on async word.

[pavel-kirienko]

Ah. Here is the culprit: https://docs.python.org/3.6/library/asyncio-task.html#asyncio.async. async is a reserved keyword starting with Python 3.7; that API function is deprecated since Python 3.4. I should update quamash to a newer version where this issue is fixed - this changeset was merged in just 4 days ago and is released under v0.6.1: https://github.com/harvimt/quamash/pull/94/files#diff-b6196c9cf4a2f8190164136b76096c05L275

[pavel-kirienko]

If you're keen on Python 3.7, perhaps you could submit a PR updating the quamash submodule? That would be appreciated.

I am interested in getting this running on OSX. I am willing to help out. What is the latest on supporting OSX. Is there a recommended minimum version of python to target?

[pavel-kirienko]

Is there a recommended minimum version of python to target?

Yes, Kucher requires Python 3.6. Let me know if you have further questions.
