Issue with Anaconda package manager - library installed, but not found in Spyder - python

I installed cairo using Anaconda Navigator (in case it's important, cairo is also installed in the other two environments: miniconda3 and spyder-env):
I launch Spyder from Anaconda Navigator, and try to import cairo, and get an error saying:
ModuleNotFoundError: No module named 'cairo'
Spyder seems to be using the correct python environment. If I run `conda list cairo', I get the following output:
What am I doing wrong?


I had problem similar to this with VaderSentiment analysis library. Jupyter notebook couldn't find it although it was installed. Either you can use a more stable Python version such as Python 3.7 for compatibility or you can use importlib.
conda install python=3.7
I solved it using importlib This does not answer your question "what am i doing wrong", but it solved the problem in my case. Just locate cairo.py in your Anaconda folder whatever the environment is. You can make necessary adjustments. I hope this helps if you have emergency to use that package.
import importlib.util
import sys
spec = importlib.util.spec_from_file_location("vaderSentiment", r"C:\Users\matt\Anaconda3\envs\sentiment\Lib\site-packages\vaderSentiment\vaderSentiment.py")
foo = importlib.util.module_from_spec(spec)
sys.modules["vaderSentiment"] = foo
spec.loader.exec_module(foo)

I couldn't import or use tdclient library

I got an error with this code:
from td.client import TDClient
Error message:
ModuleNotFoundError: No module named 'tdclient'
and I installed tdclient through the command line:
pip install td-client
and it was successfully installed.

If you are using virtual environments (venv), ensure you installed the module in the right venv.
If you are indeed using the right virtual env, or you're not using virtual environments at all, there may be a typo in the import statement.

Accessing Pattern library in Spyder

My base environment in Python 3.7. I created a new environment called Python27 (which is Python 2.7 version as I want it for Text Analytics) and is my current environment. I activated it using the command activate Python27. So, the top left corner in spyder shows as Spyder(Python 2.7)
I installed Pattern Library using pip install pattern and it got successfully installed after I resolved the C1083 error. Now I am having issues accessing it in Spyder when I type from pattern.en import suggest I get the error
ImportError: No module named pattern.en
The same issue is with spacy library. Moreover, I cant see the libraries Pattern and Spacy in conda list.
where am I going wrong?

Failed to import WordCloud from wordcloud

I installed wordcloud package for my 64 bit windows 10 system with anaconda python 3.5
using python -m pip install D:\folder\wordcloud-1.5.0-cp35-cp35m-win_amd64.whl
command.
It has been successfully installed.
But when I am trying to import from wordcloud import WordCloud,STOPWORDS, I am getting error.Please check this:
Has it something to do with the path of wordcloud-1.5.0-cp35-cp35m-win_amd64.whl file as I have placed it in some random folder?
Thank you in advance.

The simplest way to trace the error is to import the package (which apparently works) with import wordcloud and then list all members of the package with help(wordcloud). Check if the version and functions match your expectations. Check if it also matches the documentation of your package.
I suspect that the name of the WordCloudclass was simply changed.
If you miss functions then your package is broken. If the version number is wrong then you downloaded an old package. Use the Anaconda Navigator that usually comes with Anaconda to reinstall the package. If you do not have the Navigator use whatever package manager you have.

Conda openpxyl install results in No module named 'openpyxl'

I installed several conda environments with different Python versions.
After activating my Python 3.5 environment I have installed openpxyl via the line given here: https://anaconda.org/anaconda/openpyxl
However, when I try to import I get
ImportError: No module named 'openpxyl'
When I type conda list I do see
openpyxl 2.4.7 py35_0 anaconda
in the list.
(code to import is just import openpyxl or from openpyxl import *)
Any suggestions? Thanks!

You can try deleting all openpyxl material then reinstall it using pip.
that's how i solved my problem at least.

Even I faced the Same issue. This might Help you. If we have given python path in the windows environment variables which is present before we installed anaconda. We can test it by using
python --version
It will give you the version if the path is already present as
Python 3.6.5
Please remove this path of python which is already mentioned.
Then give the path of the python which is is anaconda directory. Normally it will in the path
C:\Users\lenovo\Anaconda3\
Just add this path to environment variables and again check for the python version
that might give you the following result
Python 3.6.5 :: Anaconda, Inc.
then it is confirmed that you are using the python which is downloaded using anaconda package manager.
Now you use the conda modules anywhere.

Importing mpl_toolkits.basemap on Windows?

I have recently started using Python 3.5 and Anaconda on my Windows pc. I am trying to plot a map. However, When I am in my Jupyter notebook and i type the command
import mpl_toolkits.basemap
I get an error message saying 'no module name' 'mpl_toolkits.basemap'
However, I have the module downloaded and in the same C:\Users\Geena file as my .matplotlib, .ipython, .jupyter files, etc.
Anyone know how I can fix this?

I've had this issue with anaconda on my windows 7.
I found the way to fix it with python 3.5:
You need to run with administrator rights "Anaconda Prompt" and in "Anaconda Prompt" run following command:
conda install -c conda-forge basemap-data-hires=1.0.8.dev0
, it will show new packages that you need to install and will ask you to install it - say 'Yes'.
After that new packages will be installed and the issue "import mpl_toolkits.basemap" will be fixed.
Thank you.

Currently, basemap is not compatible with python 3 for windows users. So, if you try conda install basemap and you have python 3 installed in windows, you'll see a message pointing out that a conflict was found with python 3.
I solved this by installing a python 2.7 environment. Try this:
http://conda.pydata.org/docs/py2or3.html
Then you just activate the python 2 environment. For example: activate py27 (py27 is the identifier of my python 2.7 environment).
After that, you can run conda install basemap with no conflict.

I'm using python 3.6.4 on Windows 7 Family Premium (32bit).
Because I was a bit frustrated by the message "no module named 'mpl_toolkits.basemap'", I searched for and tried a dozen of solutions without success : various versions, building from source, problems with VS version, nmake, ... You all know what I mean ;-)
I finally found a quite simple solution that works perfectly well for me :-) Here it is !
from here I downloaded basemap‑1.1.0‑cp36‑cp36m‑win32.whl
I changed the current dir to my download dir
I installed the wheel with python -m pip basemap‑1.1.0‑cp36‑cp36m‑win32.whl
I did the same for matplotlib‑2.2.3‑cp36‑cp36m‑win32.whl
You DO read the versions correctly : matplotlib 2.2.3 and basemap 1.1.0
Everything works fine for me and I finally can plot OSM POI's on a map of Belgium, without any 'trickery' at import :
import requests # to fetch OSM data
import json # to get the response
from mpl_toolkits.basemap import Basemap # ... Belgium is there !
import numpy as np # for arrays
import matplotlib.pyplot as plt # to build the populated map
Big big thanks to Christoph Gohlke (Danke Dir Christoph !) who did all the wonderful job !

When you have Anaconda, you don't download modules anywhere. In your command prompt, you type
conda install basemap
and it is installed with all its dependencies.

Anaconda requires an unusual install command for basemap 1.0.7.
https://anaconda.org/anaconda/basemap
To install this package with conda run:
conda install -c https://conda.anaconda.org/anaconda basemap

I just had this issue as well. All you need to do is update matplotlib by doing the following:
pip install --upgrade matplotlib
mpl_toolkits is part of matplotlib and just needs to be updated.

If you're using anaconda, the easiest thing to do is described here: in the conda prompt (as admin), type conda install -c anaconda basemap.

For people of the future : "Basemap is deprecated in favor of the Cartopy project."
