[PYTHON] JupyterLab3.0 Debugger Installation Method for Windows

Jupyter Lab 3.0 released

The long-awaited visual debugger is included, making it easier to use! https://blog.jupyter.org/jupyterlab-3-0-is-out-4f58385e25bb

Simply increasing the version does not enable the debugger function. The installation was unexpectedly troublesome, so I will summarize it.

Installation flow

① Installation of miniconda 　↓ ② Install xeus-python (debugger) 　↓ ③ Jupyter lab update 　↓ ④ Installation confirmation 　↓ ⑤ Reinstall the library

① Installation of miniconda

Because xeus-python is packaged for the conda package manager It is necessary to install a conda environment. Since Anaconda has competing functions, we will use miniconda with limited functions here. (If you have Anaconda installed, uninstall it)

↓ DL installation of software for each environment

https://docs.conda.io/en/latest/miniconda.html

PATH (unnecessary

Added to Path of system environment variable C: \ Users \ (username) \ Miniconda3 \ Scripts It doesn't seem to be essential unless you work on the command prompt.

② Install xeus-python (debugger)

Subsequent work was installed Perform with Anaconda Prompt (miniconda3)

https://xeus-python.readthedocs.io/en/latest/installation.html Execute the With conda code in order

xeus-python_install.py

conda create -n xeus-python
conda activate xeus-python # Or `source activate xeus-python` for conda < 4.6
conda install xeus-python jupyterlab -c conda-forge

③ Jupyter lab update

It may be the latest one in ②, but ... just in case

Jupyterlab_update.py

conda install -c conda-forge jupyterlab = 3

④ Installation confirmation

Launch Jupyter lab on Anaconda Prompt. Installation is successful if there is a description of Xpython.

⑤ Reinstall the library

Since the environment changes, reinstall the libraries you want to use (pandas, numpy ...). conda install pandas (install with conda instead of pip)

that's all.

Addendum) Every time you start it ② The problem that the debugger does not start unless you include the code of xeus-python (debugger)
