Numpy 1.16 not found

Numpy 1.16 is non-existent in my anaconda environment. Does anyone know how to properly install it? Thank you so much!

If you are using anaconda navigator, then there under Environment section, there is an option to select the specific package version to install the numpy. Will it be OK if you will elaborate your issue a further for me to get an idea that after performing what action are you getting this error.
