Installed miniconda - running python 3.10 now getting new errors about missing modules.

ModuleNotFoundError: No module named 'delegator'
ModuleNotFoundError: No module named 'telegram'

Installed those with pip, new errors:

Traceback (most recent call last):
  File "/home/ben/src/telegram-shell-bot/bot.py", line 7, in <module>
    from telegram import InlineKeyboardButton, InlineKeyboardMarkup, constants
ImportError: cannot import name 'InlineKeyboardButton' from 'telegram' (/home/ben/miniconda3/lib/python3.10/site-packages/telegram/__init__.py)

The correct dependance is

python-telegram-bot = "^13.14"
"delegator.py" = "^0.1.1"

Same errors here, i checked pyproject.toml and contains the information that @vicalloy mention:

pyproject.toml:python-telegram-bot = "^13.14"
pyproject.toml:"delegator.py" = "^0.1.1"

Any solution ?
