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 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 trying to run R in a google collab notebook (which worked fine before, however as I now tried to access it and run it it keeps giving me an error).
I have ran the following:
%load_ext rpy2.ipython
%%R
install.packages('rworldmap')
install.packages('classInt')
install.packages('reshape2')
install.packages('dplyr')
install.packages('ggpubr')
NotImplementedError: Conversion 'py2rpy' not defined for objects of type '<class 'str'>'
I have tried re-opening the notebook or creating a new one but I keep having the same issue.
This is a problem with newer versions. You must downgrade rpy: run in a cell:
!pip install rpy2==3.5.1
restart and try again
From this post.
It would be best if you first uninstalled the currently loaded rpy2 package:
!pip uninstall rpy2 -y
Then install an older version of rpy2 (3.0.0, works for me):
!pip install rpy2==3.0.0
Use magic commands and enjoy R&python interactively:
%load_ext rpy2.ipython
Example:
%%R
x<-1:5
x
What happened:
I have had Pip and Anaconda installed on my Mac. I tried to tidy up and decided to delete Anaconda since I assumed I only needed Pip for my Python programming.
My question:
I have been using jupyter notebook for my university project. Apparently, it had been installed by me using anaconda. Now that anaconda is gone, when I try running jupyter notebook, it is still looking in the deleted anaconda directory and throws the following error in the command line
/Users/username/anaconda3/bin/jupyter: No such file or directory
Furthermore, I now get this error when installing jupyter using pip3:
WARNING: The scripts jupyter, jupyter-migrate and jupyter-troubleshoot are installed in '/Users/username/Library/Python/3.8/bin' which is not on PATH.
Unfortunately, I barely have an idea of what I am doing when installing anything using the command line. Could you help me out in fixing the issue?
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 python 3 env
installed rpy2 with
conda install -c r rpy2=2.8.5
load the cell magic in jupyter notebook with
%load_ext rmagic
when I try to use R block in notebook, it gives me the error
ERROR:root:Cell magic `%%R` not found.
In a terminal:
pip install rpy2
In a notebook:
%load_ext rpy2.ipython
Then you can use %%R:
%%R
var <- c(1, 2, 3)
This is a link to the best answer I have found to the problem given on this thread:
R Notebook.
This link states that the error means that R is not configured in your DSS instance.
You need to install R manually.
The commands given on the forum post are:
Install the R packages RJSONIO and HTTR in any R console.
Install the Python package rpy2:
pip install rpy2
Afterward, they give the following link:
configure R.
I hope this is helpful and well worded.
