疑惑
由于要用到tensorflow的原因,所以我在电脑上安装了一个py3.5版本的python, 然后用 pip install jupyter notebook之后, 启动我的jupyter总是会报错,报错信息如下
ImportError: No module named 'prompt_toolkit.formatted_text'
解决方案
之前一直以为是电脑问题,后来Google后才知道原因如下:
jupyter
requires jupyter-console and ipykernel. jupyter-console==5.2.0 (the most recent)
requires prompt-toolkit<2.0.0, but ipykernel==5.0.0 (the most recent)
requires prompt-toolkit>=2.0.0. prompt-toolkit-1.0.15 ends up being installed, which results in error
This occurs when doing pip install jupyter
, in Python 3.5. It is triggered by the new release of ipykernel 5.0.0.
大致的意思就是如果在py3.5中直接用原来的命令安装就会出问题。
解决措施如下:
pip uninstall ipykernel
pip install ipykernel==4.8.0
