method one:
1. Download the nb_conda library
conda install nb_conda_kernels
2. Restart and run directly jupyter notebook:
The possible problem is that the service has not been connected, and the symbol in front of the code has always been the 【*】
solution:
uninstall jupyter notebook and reinstall
conda uninstall jupyter
conda install jupyter
You may have to download nb_conda_kernels again:
conda install nb_conda_kernels
Way two:
anaconda terminal input
python -m ipykernel install --user --name 环境名称 --display-name "环境名称"
