Issue in working stackstac in google colab

[Jimut123]

On writing this in colab, we are getting a chain of errors,

import stackstac
import pystac_client

URL = "https://earth-search.aws.element84.com/v0"
catalog = pystac_client.Client.open(URL)

stac_items = catalog.search(
    intersects=dict(type="Point", coordinates=[-105.78, 35.79]),
    collections=["sentinel-s2-l2a-cogs"],
    datetime="2020-04-01/2020-05-01"
).get_all_items()

stack = stackstac.stack(stac_items)
print(stack)

Errors:

manually install dependencies using either !pip or !apt.

On searching stackoverflow, this seems to be a different issue https://stackoverflow.com/questions/54274630/can-not-import-protocol-from-typing

Here is the notebook https://colab.research.google.com/drive/1-RZW3tnNO2sFdl3BoqI-7J0eDzHC79Rs?usp=sharing.

Can you please figure out a way of running this in google colab? I have also tried to install python 3.8 in colab, but nothing works

! sudo apt-get install python3.8 python3.8-dev python3.8-distutils python3.8-venv

stackstac requires Python 3.8 or greater. However, some very old versions mistakenly didn't specify this, so when you pip install stackstac, that's what you're getting. It's a mistake that you can install it at all in a 3.7 environment, which I'll fix momentarily: https://github.com/gjoseph92/stackstac/issues/140.

Unfortunately I can't help you figure out how to run colab with Python 3.8, but I'm sure there are plenty of resources available to learn about that.

It is working in my laptop, but I wanted to test that on colab. Thank you anyways!
