In some scenarios, to get some Python packages to work in certain environments, getting them from Anaconda was the only way that worked. If you tried installing Dlib or OpenCV 3 on Windows 64-Bit, then you know the effort it takes to get them setup, if it wasn't for Anaconda.

| OpenCV and Dlib working perfectly together, thanks to Conda |
If you check my posts on Installing Dlib on Anaconda Python on Windows, and Installing OpenCV 3 on Anaconda Python 3.5 on Windows, you know how easy it is to use conda to install them on Python 3.5 64-Bit on Windows.
But there was a catch: The Anaconda registry only had OpenCV 3.1 and Dlib 19.0 - not the latest versions.
Checking the change-logs for OpenCV 3.2, and Dlib 19.4, we were missing quite a lot of features and optimizations.
But, not anymore!
Conda-Forge has now added the conda packages for OpenCV 3.2 and Dlib 19.4.
These contain the packages for Windows, Linux, and Mac OS, for Python 2.7, 3.5, and 3.6, for 32-Bit and 64-Bit.
To install OpenCV 3.2, just run,
conda install -c conda-forge opencv=3.2.0
and, to install Dlib 19.4, just run,
conda install -c conda-forge dlib=19.4
So, now we have access to the latest versions of OpenCV and Dlib in almost any of the environments we want.

Hi Thimira,
ReplyDeleteThanks for your tutorial.
I am struggling to install cv2. This is the error I am getting.
CondaVerificationError: The package for qt located at C:\ProgramData\Anaconda2\pkgs\qt-5.6.2-vc9_1
appears to be corrupted. The path 'Library/translations/qt_gl.qm'
specified in the package manifest cannot be found.
Can't seem to get cv2 installed, how can I troubleshoot this?

Deletemake sure you install anaconda3 ver 4.4, newer versions are unable to install dlib. Use the following to install the latest opencv and dlib:
ReplyDeleteconda install -c conda-forge opencv
conda install -c conda-forge dlib
The latest version of conda is now able to install dlib and opencv without a problem.
DeleteHello, thanks for the tutorial.I would like to know which one would be better to use for Circle Like Shape Detection in Real_time. Dlib or OpenCV ?
ReplyDeleteThe deep learning based object detectors in the latest version of OpenCV would work better there.
Deleteworked with both but i find opencv more friendly
ReplyDeleteYep, OpenCV is more optimized towards computer vision algorithms, and the functions are made to be easy. Dlib on the other hand is a machine learning library, with a few computer vision algorithms built in. So it's a bit complicated to get things working on it than OpenCV.
Deleteconda command of dlib takes tooo long to execute. what to do??
ReplyDeleteWhen i copied and run like this.. it appears as the follows:..
ReplyDeleteCould you please kindly help that how to solve this problem?
(base) C:\Users\Kumar> conda install -c conda-forge opencv=3.2.0

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:
Specifications:

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.
