What does pip install mean?

I am installing this . It tells me to do this instruction.

git clone cd pytorch-fcn pip install . 

What does pip install . mean ? Which folder or file am i running by just typing dot ? setup.py ?

Basically you are specifying the location from which the pip package manager to extract the package information from.
E.g.:

# Get the Source code git clone # Change into the cloned git repository:pytorch-fcn cd pytorch-fcn # Install the package definitions from current location i.e. pytorch-fcn. pip install . 

Here is a brief description: pip executes the setup.py which loads the requirements.txt which has textual representation of the dependency packages.
