I am installing this https://github.com/wkentaro/pytorch-fcn. It tells me to do this instruction.

git clone https://github.com/wkentaro/pytorch-fcn.git
cd pytorch-fcn
pip install .

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

    As a more general answer, . in both Unix and Windows means "the current directory". – chrylis Aug 21 at 7:32
  • pip displays a page of help text, which tells you that pip install --help will give you help text specific to pip install. – Roger Lipscombe Aug 21 at 9:15

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 https://github.com/wkentaro/pytorch-fcn.git

# 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.

  • Hello thanks for the reply. I have only used pip to do installations and have no idea how it works. What do you mean by package definitions ? Is there a specific file in pytorch-fcn that pip executes ? – Kong Aug 21 at 5:20
