 To see where the <code>pip</code> command is installing a python package from, diagnosing installation issues, you can tell it to be more verbose with the <code>-vvv</code> option. It is also worth mentioning that when installing multiple packages it is advisable to install them with one command as it helps pip resolve dependencies.

-In some cases, such as TensorFlow, we provide wheels for a specific host (cpu or gpu), suffixed with <code>_cpu</code> or <code>_gpu</code>. Packages dependent on <code>tensorflow</code> will then fail to install.
-If <code>my_package</code> depends on <code>numpy</code> and <code>tensorflow</code>, then the following will allow us to install it:
-{{Commands|prompt=(ENV) [name@server ~]
-|pip install numpy tensorflow_cpu --no-index
-|pip install my_package --no-deps
-}}
-The <code>--no-deps</code> options tells <code>pip</code> to ignore dependencies.
