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.
① Installation of miniconda ↓ ② Install xeus-python (debugger) ↓ ③ Jupyter lab update ↓ ④ Installation confirmation ↓ ⑤ Reinstall the library
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)
https://docs.conda.io/en/latest/miniconda.html
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.
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
It may be the latest one in ②, but ... just in case
Jupyterlab_update.py
conda install -c conda-forge jupyterlab = 3
Launch Jupyter lab on Anaconda Prompt. Installation is successful if there is a description of Xpython.
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)
