To install the packages listed in the requirements.txt file from within a Python script, you can use the subprocess.call() function to execute the pip command with the ‘-r’ flag, followed by the path to the requirements.txt file.
Here’s an example:
1. Create a requirements.txt file and list all the packages that your project depends on, along with their version numbers.
Each package should be on a separate line. Here’s an example requirements.txt file:
matplotlib==3.2.2
pandas==1.0.5
numpy==1.19.0
2.
Import the subprocess module at the top of your Python script. 3.
Use the subprocess.call() function to execute the pip command using the ‘-r’ flag. The syntax for the command is “pip install -r path/to/requirements.txt”.
For example, to install the packages listed in the requirements.txt file located in the same directory as your Python script, use the following command: “subprocess.call([‘pip’, ‘install’, ‘-r’, ‘requirements.txt’])”. Once you run this command, all the packages listed in the requirements.txt file will be downloaded and installed on your system.
From here, you can use the installed packages in your Python script as needed. In conclusion, installing packages from within a Python script and installing packages using a requirements.txt file are useful solutions to streamline the package installation process.
