When I run the following code, I get this error. I am not sure what it means or how to correct this error.
I take it that I must download and install a new Chromedriver for Windows 10 (I choose the stable version ) and then put it in my path.
Is that all. I must do? When was this changed? I have similar software before, but never had this situation.
Any help appreciated.
