Hey @plain ember!

It looks like you pasted Python code without syntax highlighting.

Please use syntax highlighting to improve the legibility of your code and make it easier for us to help you.

To do this, use the following method:
```py
print('Hello, world!')
```

This will result in the following:

print('Hello, world!')```
You can **edit your original message** to correct your code block.

Ask your Python question, not if you can ask or if there's an expert who can help.
Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
Explain what you expect to happen and what actually happens.

i honestly dont even know whats going on but im hoping someone can help

According to the docs, the mp.solutions directory is deprecated.

Attention: Thank you for your interest in MediaPipe Solutions. As of March 1, 2023, this solution was upgraded to a new MediaPipe Solution. For more information, see the MediaPipe Solutions site.

#

Spending time getting deprecated code to work in a new project is a waste of your time

plain ember Mar 2, 2024, 2:51 AM

#

wdym by deprecated code @keen girder

#

like i shouldnt be using that directory at all?

keen girder Mar 2, 2024, 2:53 AM

#

ideally, no

plain ember Mar 2, 2024, 2:55 AM

#

do you know of an alternative?

keen girder Mar 2, 2024, 2:58 AM

#

keen girder According to [the docs](<https://mediapipe.readthedocs.io/en/latest/solutions/ha...

read this

#

I actually helped somebody with a mediapipe issue the other day

#

They too ran into issues because mediapipe deprecated a lot of stuff.

plain ember Mar 2, 2024, 3:00 AM

#

so not worth using @fading pivot

#

or whats the opinion

fading pivot Mar 2, 2024, 3:00 AM

#

I mean you can use it you'll just have to rewrite your stuff

#

read the docs on the site to see exactly what Google changed

#

They have old revisions of the package in their repo though so if you want to stick with a specific version you can do that

keen girder Mar 2, 2024, 3:01 AM

#

keen girder According to [the docs](<https://mediapipe.readthedocs.io/en/latest/solutions/ha...

read the docs instead of copying old code from an old tutorial or example

fading pivot Mar 2, 2024, 3:01 AM

#

but caveat emptor

keen girder Mar 2, 2024, 3:01 AM

#

the docs have new example code that does work

#

just in case you missed it, here's the link to the docs
https://developers.google.com/mediapipe/solutions/vision/hand_landmarker
please click one of these links to read the docs

plain ember Mar 2, 2024, 3:03 AM

#

which link @keen girder ?

keen girder Mar 2, 2024, 3:03 AM

plain ember Mar 2, 2024, 3:03 AM

#

keen girder Mar 2, 2024, 3:03 AM

#

ah you can't embed links in links

plain ember Mar 2, 2024, 3:03 AM

#

thanks for the help

keen girder Mar 2, 2024, 3:04 AM
