What's wrong with the invalidity of the python virtual environment?

the virtual environment is created by pycharm. After entering venv\ script\ activate.bat on the command line, the display enters the virtual environment, and (venv) appears. However, typing pip-V shows c:\ users\ yglin\ appdata\ local\ programs\ python\ python37\ lib\ site-packages\ pip (python 3.7)
does not mean that the virtual environment is invalid. Why?
Virtual environment is effective in pycharm
