我最近按照以下说明为我的机器学习课程安装了ipython Notebook:
第1步:创建并激活新的虚拟环境(推荐)
# Create a virtual environment named e.g. dato-env
virtualenv dato-env
# Activate the virtual environment
source dato-env/bin/activate
第2步:确保点数版本> = 7
# Make sure pip is up to date
pip install --upgrade pip
第3步:确保安装IPython和IPython Notebook
# Install IPython Notebook (optional)
pip install "ipython[notebook]"
一切正常,直到我通过输入以下命令启动ipython笔记本服务器:
ipython notebook
然后弹出以下错误:
