Conda Package Match Specification

Conda supports to specify channel where the package is sourced from and match specification of the package. So we can specify images more specifically.

The syntax is

(channel(/subdir):(namespace):)name(version(build))[key1=value1,key2=value2]

For example, to install numpy package which is sourced from the channel, conda-forge, Ref.⇗.

Use -c conda-forge:: to specify the channel:

-c conda-forge::numpy==1.17*
