I did install Python 64 bit, Any idea what can be the problem? Why I'm still getting this error?

Answer 1

Dlib is support with python 3.6 to 3.7.0 version s.Try to install the dlib in anaconda prompt by following command.,

step 1: conda create -n env_name python=3.7.0

step 2: conda activate env_name

step 3: conda install -c conda-forge dlib=19.17

-c is stands for channel, conda-forge is one of channels.

you can find all supported packages for conda's in this link https://repo.anaconda.com/pkgs/main/win-64/

Anaconda is available from, https://www.anaconda.com/distribution/#download-section
