I'm very sorry, this question has popped up quite a few times, yet I'm still struggling. I'm using Windows 11. I've installed Anaconda Navigator, created a new environment, and installed the required module (MDAnalysis, via Anaconda Navigator). I launched Juypter Notebook from the play icon of the desired environment inside Anaconda Navigator.
Then with the code:
import sys
print(sys.executable)
#!pip install mdanalysis
import mdanalysis as md
Which returns the error:
---------------------------------------------------------------------------
ModuleNotFoundError Traceback (most recent call last)
Cell In [1], line 6
1 import sys
2 print(sys.executable)
3
4 #!pip install mdanalysis
----> 6 import mdanalysis as md
ModuleNotFoundError: No module named 'mdanalysis'
As you can see, from printing out the sys.executable and checking whether mdanalysis is installed (it is; hence I commented the pip line out), I've tried attempts mentioned elsewhere in StackOverflow with no success.
The executable is:
C:\Users\yewro\anaconda3\envs\MinesMD\python.exe
Where MinesMD is the conda environment, I (a) installed MDAnalysis from Anaconda Navigator, and (b) I launched Jupyter Notebook.
I would appreciate any help/suggestions.
EDIT
I've just tried installing MDAnalysis via conda inside Jupyter Notebook. I shouldn't need to do this as I did it within Anaconda Navigator (and with the right environment), but in for a penny, in for a pound. This is the output (matching python executable location and environment):
C:\Users\yewro\anaconda3\envs\MinesMD\python.exe
Collecting package metadata (current_repodata.json): ...working... done
Solving environment: ...working... done
# All requested packages already installed.
Retrieving notices: ...working... done
Try installing the missing package directly from the Jupyter Notebook (with pip or conda) as explained here:
https://jakevdp.github.io/blog/2017/12/05/installing-python-packages-from-jupyter/
EDIT:
We figured out that the package was correctly installed and accessible to the Jupyter Notebook environment. (See comments for this answer)
The problem is that the modules import should be different: import MDAnalysis instead of import mdanalysis.

I have installed h2o package on anaconda python, however, I get the following error on jupyter notebook:
import h2o
---------------------------------------------------------------------------
ModuleNotFoundError Traceback (most recent call last)
<ipython-input-1-accdebc0c7de> in <module>
----> 1 import h2o
ModuleNotFoundError: No module named 'h2o'
From the conda list I can see that the installed h2o version is the following:
conda list h2o
#
# Name Version Build Channel
h2o 3.18.0.2 0 anaconda
(Is it normal that the build version is 0 here?)
The python version is 3.7.4.
I also tried the following
conda install -c h2oai h2o
and I get
# All requested packages already installed.
Any ideas why the h2o package isn't working?
Thanks for your time!
AMC, regarding the anaconda environments, after running:
conda info --envs
I get:
# conda environments:
#
base * C:\Users\ncham***\AppData\Local\Continuum\anaconda3
As far as I can see, there is only one environment...
Here is the official guide for installing H2O on Anaconda.
Jump to the Install on Anaconda Cloud part, make sure your Python's version is compatible with h2o module (2.7,3.5 and 3.6), follow the steps and you will be able to import h2o module through py36 channel.
Hope this answer helps you.
Tried cloning git to Jupyter folder on Windows. No progress.
I have installed SKMultilearn in the same folder as Jupyter.

ModuleNotFoundError: No module named 'skmultilearn'
I faced the same issue and couldn't find a solution. Remember, you must have installed skmultilearn first from cmd, pip install scikit-multilearn. If you have done this and still Jupyter Notebook is saying ModuleNotFoundError: No module named 'skmultilearn', then my solution is for you.
I tried and managed to find an easy solution. I hope that you might have found a solution as this question was asked 3 years ago. I am posting this because many new users will be facing this issue.
Open Jupyter Notebook terminal and go into python.
Type, help('modules'). You will get a list of all packages available to you. 99% chance is that you will not find skmultilearn in that list.
Now, go to command prompt aka cmd.
Type, pip3 install ipykernel --upgrade, then py -3 -m ipykernel install --user, you will get this, Installed kernelspec python3 in C:\Users\MC\AppData\Roaming\jupyter\kernels\python3.
Now type, pip install scikit-multilearn. It will say Requirement already satisfied: scikit-multilearn in c:\python396\lib\site-packages (0.2.0)
Good now type, pip3 install jupyter.
Then, again install pandas and seaborn as your need, pip install pandas and pip install seaborn.
Enjoy, issue resolved. You will not face this error :)
Are you sure that skmultilearn has been correctly installed? It does not depend on the subdirectory where you did the installation.
Open a terminal window in your Jupyter browser, go into python
ipython
and then check out the modules that has been installed:
[1] help('modules')
You will get a list of all packages available to you. skmultilearn should be in the list if it was correctly installed.
pip install scikit-multilearn
pip install scikit-multilearn
I'm using Anaconda 5.0.1 with Python 2.7.14. When I open a jupyter notebook and try to run the following:
%matplotlib inline
I get the following error:
ImportError Traceback (most recent call last)
C:\toolkits.win\anaconda2\envs\dlc\lib\site-packages\matplotlib\font_manager.py in <module>()
56
57 import matplotlib
---> 58 from matplotlib import afm, cbook, ft2font, rcParams, get_cachedir
59 from matplotlib.compat import subprocess
60 from matplotlib.fontconfig_pattern import (
ImportError: DLL load failed: The specified procedure could not be found.
When I try to drill into the error, the problem is with ft2font:
In [1]: from matplotlib import ft2font
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)
<ipython-input-1-a32e7826851f> in <module>()
----> 1 from matplotlib import ft2font
ImportError: DLL load failed: The specified procedure could not be found.
I double-checked and made sure freetype is installed:
(dlc) C:\Users\Larry>conda install freetype
Fetching package metadata .............
Solving package specifications: .
# All requested packages already installed.
# packages in environment at C:\toolkits.win\anaconda2\envs\dlc:
#
freetype 2.8 vc9hf582001_0 [vc9]
Any ideas?
conda install freetype --force-reinstall
Improving a bit on the above suggestion:
pip install matplotlib --force-reinstall
def _check_versions():
# Quickfix to ensure Microsoft Visual C++ redistributable
# DLLs are loaded before importing kiwisolver
from . import ft2font
Try install Microsoft Visual C++ redistributable
My solution: unstall matplotlib, and re-install it with pip.
I have the same issue and on my machine the problem was that Java (openJDK) was mentioned in the PATH-variable prior to Python (Anaconda in my case).
If you open a cmd and type
echo %PATH%
you can check if that is the case on your machine as well. If it states ...\Java\openJDK<version>\bin is before the Anaconda directories, the wrong freetype.dll library is getting found and the error occurs.
All you have to do is to change PATH to state the anaconda directories before the Java directories. This may raise another set of issues with Java though...
I found that if conda doesn't activate when the terminal starts up properly, you get this error.
I found that by opening the terminal, typing a bunch of stuff and pressing enter a a lot to prevent conda from activating and then when I tried to run a matplotlib inclusive script it would give me this error, but when I let it start without interference, it would not give me this error (it would run fine, at least past this error).
Considering this, it may be useful to keep import matplotlib at the top of the file if possible, so you don't wait a while and then find out that matplotlib won't load.
I solved this problem by installing the last Microsoft Visual C++ redistributable 2019.
In my case :
python 3.8.7
matplotlib : 20.3.3
test.py
result in IDLE
Debugged into same issue. It seems another access-deny issue.
Solution: Re-install matplotlib in elevated mode.
Launch Anaconda Prompt as Administrator
Run conda install matplotlib
Finish installing any required packages.
I got this error in Jupyter Notebook.
this may duplicate post but no any proper answer found
Neither below links helped me to solve this.
No module named tensorflow in jupyter
No module named tensor flow -- iPython notebook

ModuleNotFoundError Traceback (most recent call last)

ModuleNotFoundError: No module named 'tensorflow'
B:S -
enter image description here
I faced the same problem at first. I realized that in the conda-->envs -->
tensorflow-->Scripts-->idle.exe, is the python 3.5.5 shell. Where you can import tensorflow without any problems. So, I chaged the directory as C:\Users\Temp\Anconda3..... and then activated and deactived the tensorflow once. In the next step I entered the python mode and import tensorflow as tf worked right.
I had the same problem and I think I've found the solution!
See, I had installed both CPU and GPU versions of Tensorflow at the same time which apparently is wrong. Then, I uninstalled the GPU version, it didn't work this time either. So I uninstalled both of them and reinstalled the CPU version. It's working now.
BTW I'm on Win10(1803) and python 3.6.5 (not using anaconda.)
You can execute the following instructions and command to solve the issue: (do not include inverted commas)
Open Anaconda Prompt
type: "create --name py3-TF2.0 python = 3"
press "y" to continue
After successful completion:
type "conda activate py3-TF2.0"
type "pip install matplotlib"
type "pip install tensorflow==2.1.0"
type "conda deactivate"
type "pip install ipykernel"
type "conda install nb_conda_kernels"
Now exit the Anaconda prompt and open the Anaconda Navigator application. Switch to "py3-TF2.0" from the base environment using the Environment tab. Install Jupyter in the specified environment.
After successful installation, open Jupyter notebook and switch to "py3-TF2.0" kernel using Kernel Tab.
You're good to go for using TensorFlow 2.
Make Sure you use Anaconda 2020.02 or lower version.
As new version does not support TensorFlow 2.
I've been working in Jupyter IPython notebook (using Python 2.7) and haven't had any issues before this importing and installing packages. Most of my packages were installed via Anaconda. Now I'm randomly having problems importing packages that I've always been able to import. I have an example below. Please help. I'm pretty new to Python so I'm completing stuck on what the problem is and how to fix it.
import pandas as pd

conda virtual environments will help you a lot. It's good practice to use environments for your projects. And it'll help you avoid causing potential problems with your system's Python.
Try this on the command line:
conda create -n myenv anaconda
source activate myenv
jupyter notebook
That default env will already have pandas; you can install most other things with conda install <package> or, if that doesn't work, pip install <package>.
Running this solved the problem: pip install scipy-0.16.1-cp27-none-win_amd64.whl After doing this, all other packages were able to be re-installed and successfully imported.
