Python environment preparation (venv first time use)

** Personal memo 2 **

Creating a Python environment The PC I'm using at work is Anaconda, which was working well When I tried to create an environment for my home PC, it didn't work, so I tried another method.

Windows10 home

python install

https://www.python.org/downloads/windows/

~Windows x86-64 executable installer Drop and install

I made it Ver.3.7.7 today

I forgot to pass PATH, so I put it in the system environment variable PATH C:～\Python\Python37 C:～\Python\Python37\Scripts Added two

Use virtual environment venv

Worked with PowerShell

Move to the destination you want to save

Folder to create cd environment

Decide a name and create an environment → You can create a folder with the environment name without permission

python -m venv environment name

Activate → get stuck here

.\Environment name\Scripts\activate

"Because script execution is disabled on this system" I can't activate it somehow

Follow the above and restart Powershell with administrator privileges

Set-ExecutionPolicy RemoteSigned

Proceed with Yes

Activate again to complete

.\Environment name\Scripts\activate

Powershell display (Environment name) ~ Maybe OK because it changed to

After that, should I prepare various things with pip install ***? In Visual studio code, it worked fine when I reselected to Python in the environment I created

Things I put in today

numpy opencv-python pyrealsense2 open3d-python pandas matplotlib seaborn bokeh
