PEP 668的目的是让我们在安装Python的扩展包时,不会影响到操作系统原有的Python环境。因此,PEP 668建议我们在安装Python包时,不要直接在操作系统中安装,而应该创建一个像“小岛”一样的地方(虚拟环境venv),在这个“小岛”上安装和使用Python包。这样做的好处是这个“小岛”和操作系统是隔离的,所以不会导致任何问题。
python3 -m virtualenv --no-site-packages venv 激活环境命令为: source venv/bin/activate 注:激活环境后,输入命令的指示标志前会变成类似 (venv) pi@raspberrypi:~/www/demo $。 退出当前环境命令为: deactivate django 项目配置 环境配置好后,便可以准备项目的上传。该部分的所有命令皆是在激活虚拟环境(sourc...
Re: Bookworm & Python library hell Fri Oct 20, 2023 3:02 pm OK, maybe I deserved that (and thank you for moving this to the Python forum!) But I'm still not clear on what happens with updates and additions after the venv has been created. The Raspberry Pi documentation here: https...
One of the new features in the latest set of Raspberry Pi OS images is, for the first time, pre-installed beta release versions of the new Picamera2 Python camera library.

python -m venv tflite-envNow, we should have a virtual environment created in our tflite directory. Each time we wish to execute a TensorFlow Lite program, we must first activate the tflite-env virtual environment, as that’s where all of our packages and librari...
First of all thanks for all your effort! Your work is greatly appreciated! I've been using the luma.led_matrix package for quite a while without any issues on an RPI 3B with Raspberry Pi OS Lite (buster). Now I tried the latest Raspberry...
