The code pip install -r ../projects/radar_python_scoring_poc/requirements.txt is a command used to install Python package dependencies listed in the requirements.txt file. Here's a breakdown of its functionality:

1. pip install: This calls the Python package manager pip to install packages.

2. -r: The -r flag tells pip to read a list of package dependencies from a file, in this case, requirements.txt.

3. ../projects/radar_python_scoring_poc/requirements.txt: This specifies the relative path to the requirements.txt file. In this example, the file is located in the radar_python_scoring_poc directory, which is inside the projects directory, located one level up from the current working directory.

What Happens:

• Pip reads the requirements.txt file, which typically contains a list of required Python libraries and their version numbers (e.g., numpy==1.23.5).
• Pip downloads and installs these libraries, along with any dependencies, into the current Python environment (which could be a global or virtual environment depending on the setup).

Use Case:

This command is commonly used to set up a Python project by installing all the required dependencies listed in the requirements.txt file.
