如何在 jupyter notebook 中安装 inltk？

Question

While installing nltk I am facing this problem.

Note: you may need to restart the kernel to use updated packages.

And here is the image

Answer 1

You should either use a ! in front of your bash installation instructions like this

!pip install torch==1.4.0+cpu torchvision==0.5.0+cpu -f https://download.pytorch.org/whl/torch_stable.html

Or do it in a terminal window by clicking on File>New>Terminal and install the packages from there. To restart your kernel, click on Kernel>Restart . In general I would advise you to read an introduction to Jupyter notebooks to start .

Answer 2

!pip3 install nltk will do the job. The ! at the start, tells the notebook to run the succeeding statement as a shell command. You will see an output like this
