RuntimeError: Failed to import command at 'napari_nd_annotator:ListWidgetBB': 'numpy._DTypeMeta' object is not subscriptable
Closed this issue · 2 comments
Hello,
I got inspired by the blog post : https://focalplane.biologists.com/2023/03/30/annotating-3d-images-in-napari/ and wanted to try out the napari-nD-annotator.
I suspect some incompatibilities of packages but could not find anything wrong.
I hope you could help me to investigate the issue.
Thank you in advance for your time and support,
Marine
**Describe the bug**
I followed the instructions from the webpage: https://www.napari-hub.org/plugins/napari-nD-annotator.
Since I have already a napari virtual environment (devbio-napari-env), I installed the napari-nD-annotator from the terminal.
Then I typed in the instructions `napari -w napari-nD-annotator "Object List" "Annotation Toolbox"` and immediately got a
> Runtime Error: Failed to import command at 'napari_nd_annotator:ListWidgetBB': 'numpy._DTypeMeta' object is not subscriptable
The detailed error is in this file: [2023-08-23_Bug-napari-nD-Annotator.txt](https://github.com/bauerdavid/napari-nD-annotator/files/12416723/2023-08-23_Bug-napari-nD-Annotator.txt)
**To Reproduce**
2 possibilities:
1- to launch napari from the terminal with the options
or
2- to launch napari on its own, and then select Plugins > napari-nD-annotator > (Annotation Toolbox ) or (Slice Interpolator) or (Object List)
**Expected behavior**
I expected the napari graphical interface to launch with the plugin one of the 3 tools from napari-nD-annotator appearing.

Hey @marbre2,
thanks for the bug report! It seems that this is not related to this plugin, but opencv-python
, see the issue here: opencv/opencv#23822. They seem to have fixed this issue in the newest version, so try to update the opencv-python
package in your virtual environment.
Thank you @bauerdavid for your quick reply and for pointing to me this opencv issue.
I used the trick mentionned in opencv/opencv#23822 (comment) : manually editing the /usr/lib/python3/dist-packages/cv2/typing/init.py file by adding simple quote in several places.
It seems to quite simply solve my issue!
