Failed to execute example

[Jonas231]

Hello,

I tried to do your example:

root_pth = Path(rayoptics.file).resolve().parent opm, info = open_model(root_pth/"zemax/tests/354710-C-Zemax(ZMX).zmx", info=True)

osp = opm.optical_spec

sm = opm['seq_model']

osp = opm['optical_spec']

pm = opm['parax_model']

em = opm['ele_model']

pt = opm['part_tree']

ar = opm['analysis_results']

And get this error:

TypeError Traceback (most recent call last) Input In [36], in <cell line: 3>() 1 osp = opm.optical_spec ----> 3 sm = opm['seq_model']

TypeError: 'OpticalModel' object is not subscriptable

Best regards, Jonas

Hello Jonas, When I tried to reproduce your problem, I got an error on the first line you included. The line should be:

root_pth = Path(rayoptics.__file__).resolve().parent

with double underscores around file. When I do this, the file reads correctly for me.

Let me know if you have further problems. Sincerely,

Mike Hayford

Hello Mike, thank you for your answer. I think the error is somewhere else:

I used this code in a jupyter notebook:

%matplotlib inline

initialization

from rayoptics.environment import *

root_pth = Path(rayoptics.file).resolve().parent opm, info = open_model(root_pth/"zemax/tests/354710-C-Zemax(ZMX).zmx", info=True)

info is then listed correctly.

Then come the commands:

sm = opm['seq_model'] osp = opm['optical_spec'] pm = opm['parax_model'] em = opm['ele_model'] pt = opm['part_tree'] ar = opm['analysis_results']

Here the error occurs:

---

TypeError Traceback (most recent call last) Input In [11], in <cell line: 1>() ----> 1 sm = opm['seq_model'] 2 osp = opm['optical_spec'] 3 pm = opm['parax_model']

TypeError: 'OpticalModel' object is not subscriptable

Could you please help me remove this error message?

Regards, Jonas

The __ of file are remove due to copy and paste. I used: root_pth = Path(rayoptics.file).resolve().parent

What version of rayoptics is installed? Either use pip:

pip show rayoptics

or use the pkg_resources module:

import pkg_resources
print(pkg_resources.get_distribution('rayoptics').version)

The current version of rayoptics is 0.8.1.

Hello Mike, it seems both "pip install rayoptics" and "conda install rayoptics --channel conda-forge" installed this older version: pip show rayoptics: Name: rayoptics Version: 0.6.2 Summary: Tools for image forming optical design and analysis Home-page: https://github.com/mjhoptics/ray-optics Author: Michael J Hayford Author-email: mjhoptics@gmail.com License: BSD 3 Clause Location: c:\users\herbst\anaconda3\envs\mypython38\lib\site-packages Requires: ipython, qdarkstyle, json-tricks, matplotlib, qtconsole, attrs, transforms3d, traitlets, opticalglass, numpy, scipy, pandas, requests, ipywidgets, pyqt5 Required-by:

How do I update to 0.8.1? Best regards, Jonas

That’s odd. You should be able to force it to install a particular version, e.g.

Conda update ray optics==0.8.1.

Hope this helps.

Mike

Okay. Thank you for the idea. I get this:

(mypython38) C:\Users\herbst>Conda update ray optics==0.8.1.

CondaValueError: invalid package specification: optics==0.8.1.

[Jonas231]

I used: conda install -c conda-forge rayoptics==0.8.1 Now the example works.

[mjhoptics]

Great! I think I have my default channel set to conda-forge so I forgot it include it explicitly in my reply. Best regards, Mike
