It sounds like you have both yahoo and yfinance installed in the same environment/setup. I suggest creating a virtual environment with virtualenv so you can have the appropriate requests for each libraries.
Alternatively you can submit a PR for yahoo to use a more recent version of requests
import yfinance as yf
terminal: ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behavior is the source of the following dependency conflicts.
yahoo 0.1 requires requests==1.1.0, but you have requests 2.25.1 which is incompatible.
how can I address this issue
Regards! :)
