If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow not available for the python version you are constrained to. Note that conda will not change your python version to a different minor version unless you explicitly specify that.
Which version of TensorFlow are you trying to install? It looks like you are trying to install an older version of TensorFlow.
Try this:
conda install tensorflow==2.2
This version is supported by Python 3.8.l
open cmd and write pip install tensorflow

I'm trying to install a package from Anaconda Cloud called pyradiomics. So I wrote this Dockerfile:
FROM continuumio/miniconda3:latest
RUN conda install -c radiomics pyradiomics
which errored out with the message:
UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:
Specifications:
- pyradiomics -> python[version='>=3.8,<3.9.0a0']
Your python: python=3.7

The error message seems to indicate I need version 3.8 of python specifically, so I tried to install that
FROM continuumio/miniconda3:latest
RUN conda install -c anaconda python=3.8 && python --version && conda install -c radiomics pyradiomics
but now get the error:
UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:

Your python: python=3.8
When I have python 3.7 it wants 3.8 and when I have 3.8 it wants some other version. Is there a way to get conda to automagically resolve these version issues and install (all) the version(s) of python necessary? Or how would I best manually resolve this?
3.8 doesn't seem to be supportd as per https://pyradiomics.readthedocs.io/en/latest/installation.html#install-via-conda, though the 3.7 install conditions might contain an error.
In this case you can try to contact the authors or try with pip.
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

python >=3.6,<3.7.0a0
vc 14.*
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
I am trying to work with opencv 3.0 on my Mac OS 10.12.6
I am working with Anaconda in a python 3.5 environment, and have tried the following command in terminal:
conda install -c jlaura OpenCV3
from the following: https://anaconda.org/search?q=platform%3Aosx-64%20opencv3
However, this ends up giving the following output/error:
PackageNotFoundError: Packages missing in current channels:
opencv3 -> tbb
We have searched for the packages in the following channels:
(This is followed by a number of links, which stack overflow will not let me post as I don't have enough rep yet)
What is the best way to get opencv 3.0 on conda with a python 3.5 environment?
I need this because I am trying to implement the following: https://github.com/datitran/object_detector_app
Thanks
I essentially had to reinstall python 3.5 using:
conda install python=3.5
and then get the opencv 3.0 version like so:
conda install -c jlaura opencv3
And that did it.
I ran into the exact same problem, trying to use the same repo, however the above did not work for me. Eventually I was able to download openCV 3.0.0 by running
conda install -c memex opencv
If this has for some reason deprecated, you can always search for another option on the anaconda cloud website. Just ctrl-f for 3.0.0 and find a package that includes your platform (osx in my case).
So the question is in question and might be already answered, but I haven't found a good answer.
I use latest ubuntu 15.04 and latest anaconda with python 3.4. I want to add opencv into it (to later install caffe). To do so I used this:
https://help.ubuntu.com/community/OpenCV
Just copied the script from answer and executed it. Seems like it have completed successfully, but when I open Spyder from anaconda and do
import cv2
I get a error that no such module is found. What am I doing wrong?
BTW, when I do
conda install opencv
I get the info that package opencv conflicts with package python 3.4(!!!)
Is there any good tutorial on full install of opencv for anaconda + python 3.4?
I followed the instructions given at https://scivision.co/anaconda-python-opencv3/ This worked for me
