Flask and lab setup

In this chapter, we will continue to use a virtual environment to isolate the Python environment and dependencies. If you prefer, you can start a new virtual environment, or you can continue to use the existing virtual environment that we have been using up to this point.

In this chapter, we will install quite a few Python packages. To make life easier, I have included a requirements.txt file on this book's GitHub repository; we can use it to install all the necessary packages (remember to activate your virtual environment). You should see packages being downloaded and successfully installed at the end of the process:
