'MaterialMap' has no attribute '__annotations__'

[zstreeter]

Hi there!

Looking forward to using this project to start creating some CAD projects! Really appreciate your effort!

I followed the install instructions and tried out the verification step but resulted in the following error

  File "/home/zstreet/Documents/Repos/anchorscad/src/anchorscad/extrude.py", line 13, in <module>
    import anchorscad.core as core
  File "/home/zstreet/Documents/Repos/anchorscad/src/anchorscad/__init__.py", line 2, in <module>
    from .core import *
  File "/home/zstreet/Documents/Repos/anchorscad/src/anchorscad/core.py", line 273, in <module>
    class MaterialMap:
  File "/home/zstreet/Documents/Repos/anchorscad/src/anchorscad/datatrees.py", line 959, in wrap
    return _process_datatree(
  File "/home/zstreet/Documents/Repos/anchorscad/src/anchorscad/datatrees.py", line 876, in _process_datatree
    if OVERRIDE_FIELD_NAME in clz.__annotations__:
AttributeError: type object 'MaterialMap' has no attribute '__annotations__'

Looks like the clz class isn't being initialized correctly or something.

I'm also seeing this on the stable branch as well so I'm thinking this is on my side. Any advice would be appreciated!

Thanks for letting me know. I'm not sure. it *should* be working. I'll have a look tonight. Which version of python are you using? Anchorscad makes heavy use of dataclasses and that's changed somewhat. Come to think of it, __anotations__ is Python's place to put annotation metadata. Unless that's now changed (maybe but I think unlikely) it probably means you need a more recent version of Python. __anotations__ is used in a couple of places, including the datatrees module to check the override field state which is what seems to be happening here. On an aside, totally won't fix your issue: I've recently (like yesterday) rehashed this stuff and added Part support - (i.e. the pair Part and Material). The MaterialMap has changed. The idea is the you can associate a "part" name and priority and material and priority and it will create multiple .scad files, one for each part and one for "all". All this should not be affecting the stable to master branches. If you're interested in looking at the most recent stuff (still working on a few fixes but it builds all the modules bar 2 seem to work, checkout the dev-fobm-pmc <https://github.com/owebeeone/anchorscad/tree/dev-fobm-pmc> branch. You'll need the latest (master) pythonopenscad branch too.

Hi Zachary, https://docs.python.org/3/howto/annotations.html describes how to use __annotations__ which makes this an official Python API for classes (and other things) since Python 3.0. That would mean you're likely using Python 2.x which is not supported by AnchorSCAD. Sometimes both Python 2x and 3x are installed at the same time. Python 3.x can usually be accessed using the python3 command. See if that works for you. Best Regards g
