First, we need to install pipreqs: pip install pipreqs In order to generate project-level requirement.txt file, run the below command: pipreqs /path/to/your/project/ requirements file would be saved as- ' /path/to/your/project/ requirements.txt ' To read about more advantages of pipreqs over pip freeze , read it from here Using pipdeptree I have written a more detailed post about visual representation of python packages using 'pipdeptree' library in this blog . 'pipdeptree' provides more advanced options such as listing the dependencies in html format o
