No module named 'ezdxf.math.vector' in v8.994 BETA - fixed for next version

[Maurizio D'Addona]

The progam fails to start with ezdxf version 0.15 and throws the following error

$ flatcam 
Traceback (most recent call last):
  File "/opt/flatcam/FlatCAM.py", line 6, in <module>
    from app_Main import App
  File "/opt/flatcam/app_Main.py", line 52, in <module>

    from ezdxf.math.vector import Vector as ezdxf_vector
ModuleNotFoundError: No module named 'ezdxf.math.vector'

It seems that the class “ezdxf.math.vector.Vector” has been renamed to “ezdxf.math.Vec3“ according to the changelog (https://github.com/mozman/ezdxf/blob/master/NEWS.md)

I think that a simple way to fix this, keeping the backward compatibility with the older versions of ezdxf, is to change the line 10 of the file appParsers/ParseDXF.py from

from ezdxf.math.vector import Vector as ezdxf_vector

to

try:
    from ezdxf.math.vector import Vector as ezdxf_vector
except ImportError:
    from ezdxf.math import Vec3 as ezdxf_vector

Hi Maurizio,

As far as I can see the latest version of ezdxf is 0.14.2 but there is a beta2 version of edxf 0.15.
Thank you for the report and for the code suggestion but I will wait until the final version of ezdxf 0.15 is released. In case there are other changes.

Best regards,
Marius

The new version of ezdxf is out.

As of the ezdxf Version 0.15 - 2020-12-30, we have the following message:

ModuleNotFoundError: No module named 'ezdxf.math.vector'

This is due to:

• CHANGE: renamed ezdxf.math.Vector to Vec3, but Vector remains as synonym

See https://ezdxf.mozman.at/release-v0-15.html

The code says

from ezdxf.math.vector import Vector as ezdxf_vector

But this way, the synonym does not work.

The code should probably be changed to:

from ezdxf.math import Vector as ezdxf_vector

That has the advantage of being also compatible with older versions of the lib. (in fact, there is no ezdxf.math.vector , even in older versions)

But the try/catch as proposed above also works of course.

Issue #480 was marked as a duplicate of this issue.

Thank you all!
I’ve made the changes in my working copy, the changes will be made available on the 8.995 release.

Cheers for the suggested fix, got me up and running
