How to install opencv on windows - anaconda

I want to install face_recognition package on windows using anaconda prompt, however the official documentation says, "Windows not officially supported, but might work".
I'm getting error of OpenCV(dlib) while trying to install face_recognition.
Any help will be appreciated!

I solved my problem by the following commands:
Downgrade python for compatibility.
conda install python=3.6.0
Install dlib from conda-forge
conda install -c conda-forge dlib
Install face_recognition pkg with --no-dependencies flag to avoid installation of dlib as dependency
pip install --no-dependencies face_recognition

PyTorch dll issues for Caffe2

I am using a Windows 10 Machine and after re-installing Anaconda and all of the packages I had previously, including torchvision, torch and necessary dependencies, I am still getting this error:
OSError: [WinError 127] The specified procedure could not be found. Error loading "C:\Users\XXX\Anaconda3\envs\XXX\lib\site-packages\torch\lib\caffe2.dll" or one of its dependencies.
I am using python 3.7.9 and:
torchaudio=0.6.0=py37
torchvision=0.7.0=py37_cpu
tornado=6.0.4=py37he774522_1
traitlets=5.0.5=py_0
I've looked into it quite a bit but feel like this should be an easy solve...
I do not have CUDA and have used this:
conda install pytorch torchvision torchaudio cpuonly -c pytorch
as per instructed on the official website of pytorch
After a long time trying many things with Anaconda I decided to use bare python instead and I installed Python 3.8.6 and installed PyTorch from the link you provided and it finally worked even with CUDA support. Make sure to completely remove all Anaconda/Other Python version scripts from your path to ensure only the 3.8.6 version is used by your prompt.
I had the same problem, so I uninstalled the pytorch in my machine using
"conda uninstall pytorch torchvision torchaudio cudatoolkit=10.2 -c pytorch"
Then did a clean installation using the following
"pip install torch===1.7.0 torchvision===0.8.1 torchaudio===0.7.0 -f https://download.pytorch.org/whl/torch_stable.html"
I did not use conda for installation as it was persistently giving me the cpu version of pytorch.
I tried to install PyTorch with Anaconda and had the same error.
For me what solved the issue was to uninstall Pytorch using Pip (even though I installed it with conda) and then installing again with Pip as explains at PyTorch guide.
Uninstall:
pip uninstall torch
pip uninstall torchvision
pip uninstall torchaudio
Install:
pip3 install torch torchvision torchaudio

conflict while installing mayavi into anaconda

Good day,
My colleague asked my to install Anaconda and mayavi and I am novice with this topic and I decided to do the tasks on a new ubuntu installation
Here are my tasks before my issue
I fresh installed a Ubuntu 16.04
I ran all update apt-get update/upgrade
I created an user account (anna) and add it in sudo group
I loged into anna account
I downloaded Anaconda2-4.4.0-Linux-x86_64.sh for python 2.7
I installed with the command sudo bash Anaconda2-4.4.0-Linux-x86_64.sh
I installed anaconda in /opt/anaconda2 instead to the /home/anna/anaconda2 (for all user usage) and I say YES to have the line export PATH="/opt/anaconda2/bin:$PATH" in .bashrc file of anna
I run source /home/anna/.bashrc
After the anaconda installation, I could see a successful message regarding the installation
Now my colleague asked me to install mayavi and she provided me the following link mayavi
Then I simply enter the following command
conda install -c anaconda mayavi=4.5.0
And here start my problem. I can not well understand the conflict but apparently there is a conflict and I have no idea how to solve it. Here is the command and the message
anna#pc17:~$ conda install -c anaconda mayavi=4.5.0
Fetching package metadata ...........
Solving package specifications: .
UnsatisfiableError: The following specifications were found to be in conflict:
- mayavi 4.5.0* -> pyqt 4.* -> qt >=4.8.6,<5.0
- mayavi 4.5.0* -> pyqt 4.* -> sip >=4.16.4,<4.18
- navigator-updater -> pyqt >=5.6 -> qt 5.6.*
Use "conda info <package>" to see the dependencies for each package.
I have no idea what does mean the above message and how to solve me problem.
Is there depencies that I have to additionally install?
For information the above command return me this:
anna#cryospc17:~$ python --version
Python 2.7.13 :: Anaconda 4.4.0 (64-bit)
anna#cryospc17:~$ python3 --version
Python 3.5.2
Did I correctly try t install mayavi?
Thank a lot for any help you can provide me
To complete the install of mayavi, you have to first install the following depence
conda install -c anaconda vtk=6.3.0
conda install -c anaconda pyside=1.2.1
Then install mayavi
conda install -c anaconda mayavi=4.5.0
It may possible, you have to remove pyqt
conda uninstall pyqt
We finally could install anaconda and mayavi sucessfully.
I hope it help
Cheers
This might be helpfull to others. It must be anaconda for python 2.7 currently and the follows worked.
Install anaconda for python 2.7, then try the follows:
conda uninstall pyqt
conda uninstall navigator-updater
conda install pyqt=4
conda install vtk
conda install envisage
conda install pyside
conda install apptools=4.4.0
conda install mayavi

Tensorflow installation on Windows 10, error 'Not a supported wheel on this platform'

This question is for a Windows 10 laptop. I'm currently trying to install tensorflow, however, when I run:
pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/windows/cpu/tensorflow-1.0.0-cp35-cp35m-win_x86_64.whl
I get the following error:
tensorflow-1.0.0-cp35-cp35m-win_x86_64.whl is not a supported wheel on this platform.
I am trying to install the cpu-version only of tensorflow in an Anaconda 4.3.0 version. I had python 3.6.0 and then I downgraded to 3.5.0, none of them worked.
I also had same problem when I installed anaconda 4.3 version
Here is my solution.
Instead of using Anaconda3 4.3, install Anaconda3 4.2(Anaconda3-4.2.0-Windows-x86_64.exe)
Type on command line(If you are using GPU version)
pip install -U --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/windows/gpu/tensorflow_gpu-1.0.0-cp35-cp35m-win_amd64.whl
Typeon command line(If you are using CPU only)
pip install -U --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/windows/cpu/tensorflow-1.0.0-cp35-cp35m-win_amd64.whl
I'm working on win10 with python version=3.5.2, 64 bit
You can use same version of anaconda and execute this command
conda create -n tensorflow python=3.5
activate tensorflow
pip install tensorflow-gpu
It worked for conda 4.0.8
So are you sure you correctly downgraded your python? Run this command on command line pip -V. This should print the pip version and the python version.
Inside your Anaconda environment, try running this:
pip install --upgrade tensorflow
This will do the job. The issue was discussed here also.
Here is the screenshot of how this helped me:
If you have python3 on Windows insatalled, you can use the following command(non GPU):
pip install --upgrade https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-0.10.0-py3-none-any.whl
Worked for me.

Installing Kivy in Anaconda

I am trying to install Kivy in Anaconda 3 4.1.1 in Windows 7. But I couldn't find a proper user guide to instruct me how to do so. But so far I was able to find instructions to install it on OS X on the link https://github.com/kivy/kivy/wiki/Connecting-Kivy-with-Anaconda-(OSX). But I couldn't find a one for Windows operating systems.
Can anyone provide me with instructions on how to install Kivy in Anaconda?
Use anaconda search for search the package names and conda install to install:
anaconda search -t conda kivy
For Windows:
conda install -c krisvanneste kivy=1.8.0
For Linux:
conda install -c moritzimend kivy=1.9.0
For Mac:
conda install -c akode kivy=1.9.1
Kivy now has official Anaconda releases on all platforms. You can install it with:
conda install kivy -c conda-forge
conda install --channel https://conda.anaconda.org/jiayi_anaconda kivy
this will work fine.
