I have installed mapnik 3.0.12 with conda install -c mrterry mapnik, but why I can`t import it in my code?
import mapnik
ModuleNotFoundError: No module named 'mapnik'
I looked in anaconda3/pkgs/mapnik-3.0.12-0/lib and there is no python3.7 folder there, only .so and .a files.
I have installed mapnik with sudo apt install python3-mapnik in ubuntu 18.04 and it imports well with /usr/bin/python3 interpreter. And in directory /usr/lib/python3/dist-packages/mapnik there is some .py files.
I'm not familiar with the tool, but it looks like Mapnik is a C++ library that has separate Python bindings. You need to install both mapnik and python-mapnik. Only Python 2 is supported, so you need to create a new env for this.
Conda (only if you trust the channel)
A search of Anaconda Cloud shows only linux-64 platform is available and only from user channels. I'm following your lead on using the mrterry channel, but generally I will only use a channel if I trust the user/org.
conda create -n myenv -c mrterry python=2.7 mapnik python-mapnik
Recommended Approach
Since I don't recognize any of the channels in the search, personally I would just follow the official install instructions. First, I would set up a Conda env with Python 2.7 and the dependencies that Mapnik lists. Then activate that env, and proceed with following the instructions (./configure, make, etc.).
I want to install Opencv with contributions to my python. I am using PyCharm with conda Environment 3.6. I want to use the opencv contribution package from https://www.lfd.uci.edu/~gohlke/pythonlibs/#openpiv
But I only get "...not a supported wheel on this platform"
I tried it with pip in the terminal, also in the command promt
I tried it with conda Environment and the normal way (python 3.7.1)
I uninstalled opencv and updated pip. I tried different Version (cp36, cp37, 32 and 64-bit, 3.4.5 and also 4.0.1
I dont know anymore to do. Hope you guys can help me
Win 10, x64, Python 3.6.6 & Python 2.7.12 (I tried the code in both), IPython 6.1.0
So far I am only able to run VTK projects using Visual Studio in C++ but would like the ease of using an interpreted language for development. So I installed the latest VTK via the Anaconda command prompt, conda install -c anaconda vtk
No problems everything updated & superseded as necessary. So I tried out a trial program from the Python examples only to get...
ModuleNotFoundError: No module named 'vtk'
I added C:\Program Files (x86)\Microsoft Visual Studio\Shared\Anaconda3_64\pkgs\vtk-8.1.0-py36he6bbf13_201\Lib\site-packages\vtk to my PYTHONPATH in Spyder but I still get the same error.
Any idea why IPython cant see the vtk library?
EDIT: VTK shows up as an installed library when I type conda list at the command line
The following worked for me. Make sure to use the Anaconda Prompt.
# Create a new conda environment mypy3env and install vtk.
conda create -n "mypy3env" python=3
conda activate "mypy3env"
conda install -c conda-forge vtk
# Verify that python3 from Anaconda is used!
where python
python --version
# Test if vtk installation was successful
python -c "import vtk; print(vtk.vtkVersion.GetVTKVersion())"
See also the comments here to verify the Anaconda installation.
I tried to create a new environment and the vtk module works for Python version 3.6. When using a newer version of Python the vtk module cannot be loaded Exception has occurred: ModuleNotFoundError No module named 'vtkmodules.vtkCommonCore'(I don't know why).
conda create --name MyEnv python=3.6
conda activate MyEnv
pip install vtk
How to install opencv with python 3.6 and anaconda 3.6?
I tried conda install -c https://conda.binstar.org/menpo opencv3
but i get the following error:
UnsatisfiableError: The following specifications were found to be in conflict:
- opencv3 -> python 2.7*
- python 3.6*
Use "conda info <package>" to see the dependencies for each package.
I am using Windows 10 64-bit, with python 3.6, and anaconda 3.6 installed.
Is it even available for python3.6 at the moment or should i rollback my python version to 3.5.*?
search anaconda prompt
open and run the command.
> pip install opencv-python
this single command help's you to install opencv easily.
you can take help from the video link below.

From menpo file page, it shows that the OpenCV 3.2 binary there are only for Python 2.7/3.4/3.5 and on linux-64 platform
You may go to the this site to get the exact version you need.
opencv_python‑3.2.0‑cp36‑cp36m‑win_amd64.whl is the basic one.
opencv_python‑3.2.0+contrib‑cp36‑cp36m‑win_amd64.whl is the one
with opencv-contrib modules such as the text module for binding to tesseract OCR engine and many others.
Both binary are for OpenCV 3.2 with Python 3.6 binding for Windows 64-bit. To install it, 1) download the binary to local drive, 2) open your Anaconda command prompt and 3) type the command below in the directory the binary locates.
pip install opencv_python‑3.2.0+contrib‑cp36‑cp36m‑win_amd64.whl
Hope this help.
Update on 2018-02-22:
OpenCV 3.4.0 wheel files are now available in the unofficial site and replaced OpenCV 3.3.0
Update on 2019-01-30:
OpenCV 4.0.1 wheel files are now available in the unofficial site with CPython 3.5/3.6/3.7 support.
I managed to get it working by doing the following:
Download and install python3.6 from official python site
https://www.python.org/downloads/release/python-360/
Download and install Anaconda 4.4.0 from the official anaconda site
https://www.continuum.io/downloads
Open command line and run:
pip install opencv-python
Open command line and run:
pip install opencv-contrib-python
I am using Windows 10 and it worked for me.
It's pretty simple..
Install Anaconda 3.6. Check anaconda is added to System Variable Path.
Open CMD and type conda install -c conda-forge opencv.
This will install latest OpenCV version available (3.6).
Open IDE editor and try import cv2.
It will probably don't work...don't worry.
You have to add cv2 command to editor.
For Eclipse (with PyDev):
Create firs a project and then do the following:
For PyCharm:
cv2 module probably won't work. Go to the Anaconda folder/Lib/site-packages/cv2 and copy the file cv2.cp36-win_amd64.pyd to the site-packages folder. Rename it cv2.pyd
Now try to write a command... cv2.imread(). If auto-completition don't work, try cv2.cv2.imread().
This will work for sure.
I am using Python 3.6.2 and Anaconda 4.3.23 (It should also work with your case).
I did the following:
Download the Numpy version corresponding to your Python installation from here. In my case, I’ve used numpy-1.13.1+mkl-cp36-cp36m-win_amd64.whl
Download the OpenCV version corresponding to your Python installation from here. In my case, I’ve used opencv_python-3.3.0-cp36-cp36m-win_amd64.whl
Now go to the folder where you downloaded these files and run the following:
pip install numpy-1.13.1+mkl-cp36-cp36m-win_amd64.whl
pip install opencv_python-3.3.0-cp36-cp36m-win_amd64.whl
Note the Successfully installed … message after each command.
At this point, you should be able to play with OpenCV and Python. Let’s try a small test first. Start the Python interpreter or Jupyter Notebook and write:
import cv2
print(cv2.__version__)
If everything was correctly installed, you should see the version number of your OpenCV install, in my case this was 3.3.0.
I see you found a solution but this may be helpful for others. The package is not available for Python 3.6. You can check this by going to that package channel on anaconda.org and selecting the files tab. You will see the package tarballs with the Python version listed as py27, py34, py35,etc. This is a good way to check for Python versions of a specific package.
You can also run the following to see the package versions and Python versions available for your OS from the Anaconda channel:
conda search <package_name>
Or to search a particular channel and package you can do this:
conda search -c <channel_name> <package_name>
As of March 2018, OpenCV 3.4 can be installed directly from conda-forge or anaconda in Windows/OSX/Linux for Python 3.6
conda install -c conda-forge opencv
or
conda install -c anaconda opencv
Using:
conda install -c conda-forge opencv
worked for me
If you have installed anaconda then you should uninstall it, then try
pip install opencv_python‑3.2.0+contrib‑cp36‑cp36m‑win_amd64.whl
It worked for me.
Thank You.
I am using python 3.6 and the following worked for me:
Download and install opencv (Win pack) on your computer from the official website:
https://opencv.org/releases.html (I took version 3.4.2)
Go to the website of Christoph Gohlke and download the wheel file corresponding to your system. (I took opencv_python-3.4.2-cp36-cp36m-win_amd64.whl)
As mentioned on the website of Christoph Gohlke, make sure you installed 'numpy1.14' & 'mkl' package. Also make sure you use pip with version 9 or newer.
Start the 'Anaconda Prompt'
Change the directory in the 'Anaconda Prompt' to the folder where you downloaded the wheel file from Gohlke's website (via the MS-DOS command 'cd').
In the 'Anaconda Prompt' type 'pip install opencv_python-3.4.2-cp36-cp36m-win_amd64.whl') (change the name of the wheel file accordingly).
When starting spyder, test your installation as follows:
import cv2
print(cv2.__version__)
If the version is printed in the console (in my case 3.4.2), your installation was successful.
IMPORTANT REMARK:
If you created a dedicated environment within Anaconda (in my case 'py36'), make sure you installed spyder for this dedicated environment ('conda install spyder'). If not, your installation of opencv will not be recognised within the environment you are working in. Maybe this is obvious and straightforward but in my case I struggled to find this solution.
First Download Anaconda Python 3.6 from official site. After installing anaconda, simply open command prompt and type following statement and press enter of course -
conda install -c conda-forge opencv
It may take some time. After the completion, check your conda packages by typing conda list - opencv should be there.
However, Before proceed to install opencv, you can check whether opencv for python 3.6 is available or not. We can check it by typing conda info opencv in command prompt and press enter of course, you'll see following -
opencv 3.3.1 py36h20b85fd_1

zlib >=1.2.11,<1.3.0a0
By this we can also get ensure that opencv 3.3.1 py36h20b85fd_1 is available. And this is available for python 3.6
I think this way is straight forward. Just install anaconda from official page and follow the image.
Using Anaconda3's package manager directly will be more reliable and cross-platform:
conda install opencv
What I did to try and solve this issue:
Using Mac OS X
Using Anaconda distro currently in my computer as the path /Users/hongshuhong/anaconda/
Used conda instead of virtualenv because of my distribution of python. I referred to the guide here and tried to download the same with conda's package manager: https://www.tensorflow.org/versions/master/get_started/os_setup.html#download-and-setup
Tensorflow worked correctly when I created an anaconda env using the command conda create --name ML python=2.7 anaconda to state I'm using 2.7 python, then used this command conda install -c https://conda.anaconda.org/jjhelmus tensorflow
gathered from the Anaconda Cloud to attempt to download it. It worked when I said
$ python
>>> import tensorflow as tf
...
However, it doesn't really fix the issue:
However, I want to use the 3.5 distribution of python, simply to keep up with the times and not use outdated pythons.
I attempted to download it using the same way in python=3.5, but it raised this error when I tried to run the command conda install -c https://conda.anaconda.org/jjhelmus tensorflow :
Hint: the following packages conflict with each other:
- tensorflow
- python 3.5*
Use 'conda info tensorflow' etc. to see the dependencies for each package.
And I ran the conda info tensorflow to see what was going on and I got:
Fetching package metadata: ....
Error: No packages found in current osx-64 channels matching: tensorflow
This is really frustrating me and I'm not sure what to do. If there's no work around for this, I think I'll have to use Anaconda's python 2.7 distribution for TensorFlow experiments. If anyone has any idea how to solve this compatibility issue(or some other kind of issue), I'd be extremely grateful. Thanks.
EDIT: I'm pretty sure TensorFlow supports 3.5 because in their documentations they say they support 2.7 python and 3.3+. If there were no clues as to whether they support 3.5, I would have already given up and used 2.7 by now.
The version of TensorFlow packaged here is version 0.5.
Python 3.x support was introduced in TensorFlow 0.6, so you need to figure out how to install the newest version into Anaconda.
Usually you can install packages into anaconda using pip, but I haven't succeeded with TensorFlow.
EDIT: I just noticed that the documentation hasn't updated the url to the pip-wheel.
To install tensorflow in python 3.5 via pip, use the following command:
$ sudo easy_install --upgrade six
$ sudo pip install --upgrade https://storage.googleapis.com/tensorflow/mac/tensorflow-0.6.0-py3-none-any.whl
This links to ...tensorflow-0.5.0-py2-none-any.whl, which is an older version of tensorflow for python 2.x.
