Running scripts that need other libs installed

[backslashV]

Can I run python scripts that depend on some external libraries (like selenium, BeautifulSoup, and chromium) using pyscript? currently I'm running the script on my rPi and just sending the result to HA. I'd like to run it locally.

I'm not sure I fully understand your question. Pyscript can import external packages, but those packages need to be installed (eg, via pip) on the same host or container that HA is running in. So in your case those packages would need to be installed on the rPi.

Thank you for your response. Installing packages is exactly the problem as HA terminal doesn't recognize the pip command.

I haven't tested this, but try putting your external package requirements in the file config/pyscript/requirements.txt. Just list the packages one per line (you can also specify the version too with package_name==version). Pyscript should then install those packages if they are not already available.

Thanks. It can't find webdriver from the selenium lib.
Exception in </config/pyscript/scraper_linux.py> line 2: from selenium import webdriver ^ AttributeError: module 'selenium' has no attribute 'webdriver'
Also, how do I install the chromium-browser? I also need the chromedriver. Where can I put the binaries for the driver and what path should I use in the script?

I am trying to do the same and getting the same errors regarding the selenium webdriver. Placed "selenium" in requirements.txt
Exception in </config/pyscript/login_startcharging.py> line 1: from selenium import webdriver ^ AttributeError: module 'selenium' has no attribute 'webdriver'

The issue here is the selenium also requires the installation of a web driver, which is not installable via pip. requirements.txt only handles pip installations. So you'll need to find some other way to install the driver on your HASS instance, which may be difficult and is mostly undocumented depending on how you've installed HASS.

Any luck here?

I am trying to build an application / scraper that relies on being logged into a certain website. I see Selenium as an option to allow the user to manually login to allow the scrpaing to take place but I would need to automate the download of the driver. Maybe something like this?

Nope. Gave up on it.
