Cannot run example_runner.py

[swoker]

Hi,

First of all, thanks for the work!
Also, I don't have ANY experience in python except running a few small scripts, so please bear with me :)

I tried to run the example_runner.py and ran into multiple problems.

1. Numpy

Traceback (most recent call last):
  File "/vagrant/cqindustry/example_runner.py", line 3, in <module>
    import example.barrier.barrier
  File "/vagrant/cqindustry/example/barrier/barrier.py", line 1, in <module>

    raise AttributeError("module {!r} has no attribute "
AttributeError: module 'numpy' has no attribute 'bool8'. Did you mean: 'bool'?

It seems there's a hidden dependency for numpy <=1.23, but everytime I run the pip install cqindustry - numpy 2.1.3 is installed.
I have to revert it with pip install mxnet-mkl==1.6.0 numpy==1.23.1

2. cqspoolterrain missing

vagrant@ubuntu-focal:/vagrant/cqindustry$ python3 example_runner.py
Barrier Examples
Bridge Examples
Chip Tower Examples
Can Tower Examples
Traceback (most recent call last):
  File "/vagrant/cqindustry/example_runner.py", line 24, in <module>
    import example.can.can_platform
  File "/vagrant/cqindustry/example/can/can_platform.py", line 2, in <module>
    from cqindustry.can import CanPlatform

    from cqspoolterrain.pipe import straight
ModuleNotFoundError: No module named 'cqspoolterrain'

running this fixed the issue.

pip install git+https://github.com/medicationforall/cqspoolterrain
Successfully installed cadqueryhelper-0.2.1 cqindustry-0.1.1 cqspoolterrain-1.3.0 cqterrain-0.3.3 numpy-2.1.3
pip install ./
pip install mxnet-mkl==1.6.0 numpy==1.23.1

I had to reinstall numpy and the current package to use cqindustry-2.0.0 instead of 0.1.1 again

I guess this needs to be added in pyproject.toml?

3. error in cqspoolterrain

    from cqindustry import (
ImportError: cannot import name 'barrier_straight' from 'cqindustry' (unknown location)

it seems there's an issue inside the cqspoolterrain with the import, but I'm out of ideas how to fix this one without learning python first... :D

I think I can already create my chip tower based on the given examples, but it would be great to be able to run all examples.
Again, I have no idea about python, so please let me know if it's a user error on my side :)

Thanks!
Best
Simon

@swoker I appreciate the report! I'll poke at it when I get home.

Just out of curiosity what version of python is your linux running?
python3 --version

I don't do much in the way of linux testing so I appreciate the feedback.

[swoker]

Python 3.10.12

[medicationforall]

@swoker after poking around a bit I'm guessing the issue your hitting may be related to this issue
CadQuery/cadquery#1626

I'll check to see if there is any updates to cadquery

when All is said and done the version of cadquery I'm trying to run with is coming from one of my component libraries cadqueryhelper
https://github.com/medicationforall/cadqueryhelper/blob/main/pyproject.toml

And the version it's trying to resolve is cadquery>=2.4 which I believe is relatively up to date:
https://pypi.org/project/cadquery/#history

To get the script working you may have to mess around with the suggested workaround in the cadquery ticket
CadQuery/cadquery#1626

If you need a specific version of numpy to get the script working you can create a virtual environment I don't expect you to change your numpy version globally https://docs.python.org/3/library/venv.html

[medicationforall]

Steps to reproduce:

1. cut a new virtual environment

• mkvirtualenv industrybug

2. ran pip install .
3. ran python example_runner.py

[medicationforall]

Found a supporting bug
CadQuery/cadquery#1714

I'll attempt to add an old numpy version requirement to my project file and see if that helps for the time being.

[medicationforall]

I got over the numpy version issue but I introduced a cyclical dependency between cqindustry and cqspoolterrain

cqspoolterrain install cqindustry 0.1.1 but the version were attempting run of cqindustry is 2.0.0. I need to move some code from cqspoolterrain down into cqterrain

[medicationforall]

@swoker There was a mountain of molehills that you found, which I appreciate.

Please test with the latest release of cqindustry and see if the example_runner.py works for you.
With your confirmation I'll close the ticket.

• Moved pipes from cqspoolterrain into into cqterrain
• Moved barrier from cqindustry into cqterrain
• Moved walkway from cqindustry into cqterrain
• Cleaned up circular dependencies of cqindustry and cqindustry referring to each other.
• I ended hard coding the versions of cadquery, numpy and nlopt in cadqueryhelper medicationforall/cadqueryhelper@1.2.5...1.3.0
  I'm happy to clean up the dependency chain when a new version of cadquery releases.

Releases:
cadqueryhelper 1.3.0 - fix numpy version issue
cqterrain 2.0.0, 2.0.1, 2.0.2 - move down cyclical dependencies
cqindustry 2.0.0, 2.0.1
cqspoolterrain - next in line to get updated

Hi there,

I uninstalled everything, did a git pull, pip install ./ and ran the examples again.
It worked without any errors and created 19 STLs for Bridge Examples, Chip Tower Examples and Can Tower Examples.

Much less as before, but as you mentioned there are quite a few packages to use instead :)

Thanks for the quick fix, I will close the ticket as well
