There is error of : 'conda' is not recognized as an internal or external command,
operable program or batch file. How to remove this?

hi, why isn't it possible to install opencv the same way as matplotlib? " conda install opencv2" or something like this?

Hi Ashwin I follow with great interest your tutorials and can benefit a lot. Thank you for this.
I work on a PI3 with python3 and run into troubles when importing
>>> import matplotlib.pyplot as plt
Traceback (most recent call last):

SyntaxError: Missing parentheses in call to 'print'

The pip list shows that I have installed gi
gi 1.2

Any hint what the issue could be?
Thank you in advance.
