Bug

As of 2023-04-06, there is a somewhat obscure problem in

https://github.com/roboflow-ai/notebooks/blob/main/notebooks/zero-shot-object-detection-with-grounding-dino.ipynb

If you go back to load new images after running the demo, you get a locale related exception. System calls require an UTF-8 locale, and it is changed to something else on the way, I do not know where.

The locale changes from UTF-8 at some point, I think after running the demo. After this, calls to the system do not longer work. they fail like this:

!wget -q https://media.roboflow.com/notebooks/examples/dog.jpeg

NotImplementedError                       Traceback (most recent call last)

[<ipython-input-117-bbf546bacccd>](https://localhost:8080/#) in <cell line: 1>()
----> 1 get_ipython().system('wget -q https://media.roboflow.com/notebooks/examples/dog.jpeg')

[/usr/local/lib/python3.9/dist-packages/google/colab/_system_commands.py](https://localhost:8080/#) in _run_command(cmd, clear_streamed_output)
    165   locale_encoding = locale.getpreferredencoding()
    166   if locale_encoding != _ENCODING:
--> 167     raise NotImplementedError(
    168         'A UTF-8 locale is required. Got {}'.format(locale_encoding)
    169     )

NotImplementedError: A UTF-8 locale is required. Got ANSI_X3.4-1968

So "!wget ..." does not work. My workaround was replacing "!": python: # Run the command with a specific encoding (UTF-8) def shell(command): print(subprocess.run(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True, text=True, encoding="UTF-8"))

After running that in a new cell, this works: %cd {HOME}/data shell("wget ...") works.

I think the problem has no effect when running the notebook cells in order, but it does when goung back to load more example images with wget.

Environment

Colab

Minimal Reproducible Example

Run the notebook up to the demo, then go back to the cell with wget and try to load more example images.

!wget -q https://media.roboflow.com/notebooks/examples/dog.jpeg

NotImplementedError                       Traceback (most recent call last)

Hi, @vsiegel 👋🏻! Do you think that error originates in the supervision package?

[SkalskiP]

Hi, @vsiegel do you still experience that problem?

[SkalskiP]

I think that issue is not related to supervision but to Grounding DINO.
