So, I have installed rpy2 successfully, and I can import it in a python shell, for example. Also, I have Jupyter notebook successfully installed. But for some reason I cannot import rpy2 on the jupyter notebook. I get the standard 'module not found' error. Other posts have addressed problems relating to installation of rpy2 itself, but specifically, I can't import ONLY from jupyter notebook. I find it quite strange, because I'm fairly certain I only have one copy of Python 3.6, so why can it import in the terminal but not in the notebook. .. .
I solved this by re-installing jupyter notebook. . .
I encountered the same issue, and I use many different env with conda. Here is my solution, starting your jupyter notebook with the same env which rpy2 is installed.

I have a conda virtual environment with Python 3.7.16 and several installed libraries such as 'lifelines', etc. In the conda console all the installed libraries are shown; however, when I open a Jupyter Notebook on the same environment and try to load, for example, the library 'lifelines', it gives me the error message ModuleNotFoundError: No module named 'lifelines'.
I have searched on Github and Stack Overflow, and tried several solutions such as this one and others, but I still can't import libraries on Jupyter Notebooks that are already installed in the conda environment.
Does anybody know how to solve this issue?
In fact, I needed to install Jupyter-lab and notebook in the same environment; otherwise it was searching for all libraries in the base one.
I am using python version 3.7.12 in sagemaker jupyter notebook.
I could do a !pip install fiftyone in the notebook but when I am trying to import fiftyone as fo it is giving me below error:
ConnectionError: Could not connect to 'mongod'
I have gone through its github repository but couldn't find a way to resolve this issue. And I tried implementing some of the answers provided for fiftyone's installation in Linux but it didn't work either.
I am running Anaconda 10.0 Jupyter Notebook Python 3.8, bokeh 2.3.0 on Chrome. On my other PC (should be identical setup, except this is a slightly later Anaconda version) images are fine, but on this there is no image and the Javascript console tells me:
Bokeh: ERROR: Unable to run BokehJS code because BokehJS library is missing
I could not find a simple, working solution to this problem here or elsewhere on the net and I am at a total loss now.
The abbreviated code I'm running is:
import regex as rg
import pandas as pd
import numpy as np
import datashader as ds, colorcet
import holoviews as hv
from holoviews.operation.datashader import datashade
from holoviews import opts
hv.extension("bokeh")
datashade(hv.Points(df_re), cmap=colorcet.fire).relabel('Reflectances').opts(height=700, width=800)
Where is the problem and how should I fix it?
Unfortunately that didn't work for me, still the same error.
What I found interesting was that prior to installing ver. 1.0.3 of the extension, Anaconda prompt said:
(Datashader-Holoview) C:\Windows\system32>jupyter labextension list
JupyterLab v2.2.6
No installed extensions
It is as if no version of that extension did exist in the environment.
There might be a bug with the most recent pyviz jupyter labextension (1.0.4). See if it works for you after you do
jupyter labextension install #pyviz/jupyterlab_pyviz#1.0.3
This worked for me.
I get this error when trying to execute the imports, i've tried to reinstall python3, ipython and jupyter-notebook, but i keep getting the error ModuleNotFound. I've tried googling and searching for an answer, but nothing has worked so far. I'm new to jupyter-notebook and need it for a course.
First, install matplotlib and numpy in your terminal:
pip install matplotlib #add "sudo" before "pip" when you get "Permission denied"
pip install numpy
Then, choose the right Python version(i.e. kernel) for your notebook.
I installed pytorch using anaconda3 and my created virtual conda environment named 'torchTest'.
I installed all the modules needed but, codes doesn't work in jupyter python.
I installed torchtext using
1.pip install https://github.com/pytorch/text/archive/master.zip
2.and also pip install torchtext too.
all I mentioned successfully downloaded in my MAC OS X, but can't get what's wrong with my Jupyter notebook..
After having the same issue with torchtext from within my jupyterlab, I opened an issue on Github at the jupyterlab project as well as at the torchtext repository.
My current solution is to add the PYTHONPATH from the Anaconda env.
The Anaconda path is usually like that $HOME/anaconda/bin
You can add it from within Jupyter Lab/Notebook like that:
import sys
sys.path.append("/some/path/to/add")
import torchtext
