Different out when using conda list and pip list

[Led_Zeppelin]

What does it mean when pip list and conda list return the same file in my case numpy, but with different versions?

pip list
numpy 1.20.2

conda list
numpy 1.19.5

Of course, this is the same environment in each case - there is only one. I may be getting other conflicts in version numbers, but this is the one I spotted.

I use pip install and conda interchangeably when I am installing libraries in an environment.

I am just curious. My program is not running now.

Respectfully,
