无法将情节导入 Jupyter Notebook

Question

我是 Python 的新手，我使用命令pip install plotly使用 Anaconda 提示符安装了 plotly 库，它显示它安装在已安装的库下，但当我尝试通过 Jupyter 库导入时没有被导入，说找不到模块。

Answer 1

This is typically due to multiple Python interpreters being installed, so the Python you see in the notebook is probably not the Python you used to install plotly.

You can check this by looking at sys.executable and sys.path , and comparing those with where pip in the Anaconda prompt where you ran pip install plotly .

You can make sure to use the right Python by doing:

C:\full\path\to\right\python.exe -m pip install plotly

This should be the same as sys.executable in your notebook.

Answer 2

I had the similar issue. Go to Anaconda prompt and type pip install plotly hit enter. Restart the kernel and try importing it again.

Answer 3

Going further feom @minrk answer:

After a while searching about this problem, I discovered it is a broken conda-kernel trough jupyter notebook issue.

Inside your notebook check if it is pointing to the write python executable's envinronment path by using minrk solution:

import sys
sys.executable 

# >>>> 'C:\\Users\\username\\AppData\\Local\\Continuum\\anaconda3\\envs\\**wrong_env**\\python.exe'

If it isn't , the simple solution is to install nb_conda :

conda install nb_conda
