jupyter notebook 使用 conda virtual 環境

我已經查了前後快 五 次了!!!!!

正常來說，第三次應該就要寫筆記了~~~

看看我多認真！　都沒時間認真寫筆記　

conda vitrual 環境建立

• conda create -n NAME python=version

  • ex:

     conda create -n test python=3.6.8
    

看所有 conda virtual envs

• conda env list

  • ex:

     (base) C:\Users\tim23>conda env list
     # conda environments:
     #
     base                  *  C:\Users\tim23\AppData\Local\Continuum\anaconda3
     ai_academy_1             C:\Users\tim23\AppData\Local\Continuum\anaconda3\envs\ai_academy_1
     ai_music                 C:\Users\tim23\AppData\Local\Continuum\anaconda3\envs\ai_music
     cv_tuseday               C:\Users\tim23\AppData\Local\Continuum\anaconda3\envs\cv_tuseday
     face_recog               C:\Users\tim23\AppData\Local\Continuum\anaconda3\envs\face_recog
     mask_rcnn                C:\Users\tim23\AppData\Local\Continuum\anaconda3\envs\mask_rcnn
     monday_nlp               C:\Users\tim23\AppData\Local\Continuum\anaconda3\envs\monday_nlp
     python-cvcourse          C:\Users\tim23\AppData\Local\Continuum\anaconda3\envs\python-cvcourse
     stnadford                C:\Users\tim23\AppData\Local\Continuum\anaconda3\envs\stnadford
     yolo_darkflow            C:\Users\tim23\AppData\Local\Continuum\anaconda3\envs\yolo_darkflow
    

使用想要的 virtual envs

• activate NAME

  • ex:

     (base) C:\Users\tim23>activate face_recog
          
     (face_recog) C:\Users\tim23>
    

安裝 jupyter-notebook jupyterlab

• pip insatll jupyter jupyterlab

安裝 ipykernel

• pip install ipykernel

將此 conda virtual env 加入到　ipykernel

• doc

• python -m ipykernel install –user –name conda-virtual-env-name –display-name NAME

  • ex:

     (face_recog) C:\Users\tim23>python -m ipykernel install --user --name face_recog --display-name "face_recog_1"
     Installed kernelspec face_recog in C:\Users\tim23\AppData\Roaming\jupyter\kernels\face_recog
    

跑 jupyter-notebook

• jupyter notebook

可看到匯入的 ipykernel

• tree

• lab

jupyter notebook 架構

• doc

• 這張圖多少可以解釋為什麼，kernels 可更換
