virtual environment virtual environment

The environment where we run the code now is on PyCharm , and VScode or Jupyter that we will come into contact with in the future , whether it is debugging or running, it is more or less a graphical interface. But in fact, when the code is deployed to the server, we are more faced with black window programming, there is no smart prompt, no error prompt, and no one-click operation. We can of course edit the code completely and put it on the server. But the most basic operations on the server should still be mastered. Here we only target Windows users, because Windows terminal commands are quite different from Linux . If you are using a Mac ( the further packaging operating system of the Unix system), you can directly ignore this virtual environment installation.

install virtual machine

The virtual machine is VMware , just because it is more popular, if you can find free virtual machine software, it is

If the above prompt appears during the installation, it means that the configuration of the computer itself is disabled. Because the models of different computers are different, it is impossible to achieve unified deployment. You need to find the relevant BIOS settings on the Internet and modify them.
