I keep getting ModuleNotFoundError: No module named 'dotenv' when i try to move my API key to an environment variable, any ideas why? Thank you

edit fixed, I had to change the settings in VS code to run in integrated terminal. File > settings > Code-runner: Run in terminal [tick this]

Hi leon. which python environment is used in this video, anaconda, miniconda. Or which other one is production friendly ?

[harshvardhan]

does this project have rag implementations

[squiddymute]

i'm getting an error with 'code': 'insufficient_quota'

[blender_wiki]

Nice tutorial, however i personally prefer using anaconda in dev and miniconda for production.

[edriwingdecyan]

on MAC the command is not
venv\Scripts\activate
but
venv/bin/activate
I searched a long time...

[dipanshuasri]

I am getting below error : Error code: 429 - {'error': {'message': 'You exceeded your current quota, please check your plan and billing details. But I trie dto login with my new gmail account. and still it show's the same. I think the mistake i did is to us ethe same mobile number while generating the api key
