无法在 jupyter notebook 中导入已安装的软件包

Question

If I run the following in a Jupyter notebook :

!pip install gTTS

from gtts import gTTS 

I get the following output:

Requirement already satisfied: gTTS in c:\users\username\.conda\envs\gpu\lib\site-packages (2.0.4)
Requirement already satisfied: click in c:\users\username\.conda\envs\gpu\lib\site-packages (from gTTS) (7.0)

ModuleNotFoundError: No module named 'gtts'

What should I do?

Edit: from gtts import gTTS works perfectly fine in the terminal.

Update:

TL;DR: Still facing this problem

Even after 5 months I haven't been able to narrow down what the problem is. The answers below are workarounds but don't actually address the main problem. Why is this happening? And jupyter notebook isn't the only tool where I am facing this issue. This is a similar question I asked titled "VSCode terminal doesn't activate conda environment". Similarly with Sublime text. I can't set up the internal console to build from environments.

Answer 1

try:

!conda install gTTS
from gtts import gTTS 

Because you are using Conda, conda should be used instead of pip

Answer 2

pip install version to your default python version which is python2, you should do

!python3 -m pip install gTTS
from gtts import gTTs
