can't import cadquery

[RemDelaporteMathurin]

How to reproduce the issue:

1. Run:

docker run -it ghcr.io/fusion-energy/fusion-neutronics-workflow

using the latest tag

2. Navigate to the examples folder:

cd examples/example_01_single_volume_cell_tally/

3. Run

python 1_create_cad_and_convert_to_dagmc.py

This produces:

Subsenquently, I can't import paramak either

Hi Remi, sorry for this bug. Thanks for reporting. I spotted the same bug on my last PR from develop to main and starting fixing this bug. I shall get back to it today.

This bug is due to the dockerfile installing paramak version 0.7 instead of the newer versions such as 0.8.1

[RemDelaporteMathurin]

I don't think so cause I can also reproduce the error without importing paramak:

1. docker run -it --rm ghcr.io/fusion-energy/fusion-neutronics-workflow
2. run python
3. run import cadquery

This bug is due to the dockerfile installing paramak version 0.7 instead of the newer versions such as 0.8.1

Updating to paramak 0.8.1 didn't fix it apparently

Installing cadquery-master in a conda environment did not produce the issue:

conda create --name cadquery_temp
conda activate cadquery_temp
conda install -c cadquery -c conda-forge cadquery=master
python

import cadquery

I think the latest release has fixed this error, both CI test routines are working again. Please reopen if this problem persists
