This is the Error I’m getting while installing dlib using pip in command prompt.
I already have openCV and matplotlib and numpy.
Answers:
I faced many error while installing dlib and solve by using below .whl:
pip install https://pypi.python.org/packages/da/06/bd3e241c4eb0a662914b3b4875fc52dd176a9db0d4a2c915ac2ad8800e9e/dlib-19.7.0-cp36-cp36m-win_amd64.whl#md5=b7330a5b2d46420343fbed5df69e6a3f
Download wheel from this link
This might help 🙂
I faced the same problem a while back. I did a few things and it worked
-
Install C and C++ compilers and add them to path.
-
Install visual studio 2015 (VS2015) down-loader. (any other version might not work). This stack overflow thread may help: How to download Visual Studio Community Edition 2015 (not 2017)
-
Install all the dependencies through VS2015.(support for C, C++, MS Build, windows SDK etc)
- Try and use pip install dlib again.
I hope this helps!
You may need to install cmake first: “pip install cmake“
Then install dlib i.e: “pip install dlib“.
Will surely work 100%.
Note: You must have a fast processor for building wheel else it’ll take more than 5mins.
For those who are facing the same problem but using mac OS –> I did the below steps and resolved the same issue. I have macOS Big Sur 11.1 with python 3.8.3.
pip3 install cmake
pip3 install dlib
OK for the record here: On debian 10. pip install dlib fails even with pip install cmake first. Solution? sudo apt install libopenblas-dev. The output of pip install dlib --verbose mentions it as an optional install that makes your code run faster. Turns out without installing this first the install fails every time. With it the install succeeds.
download cmake executable file on your pc, install it and install cmake build tools for c++ from visual studio build tools. After installing cmake with visual studio build tools, you can download the wheel file from this github repo: https://github.com/Tobyyosoba777/Computer-Vision-OpenCv-Python-/tree/main/Libraries
download: dlib-19.22.99-cp39-cp39-win_amd64.whl
and download: dlib-19.22.99.win-amd64-py3.9.exe
install the .exe file on your pc, restart it(not necessary) and open the current directory of the downloaded .whl file where it is saved on your pc in your python/anaconda terminal/ cmd
for example:
C:UsersUSER->cd desktop "if you downloaded the file to your desktop" this command will move you to the current directory of the .whl file
then input: "pip install dlib-19.22.99-cp39-cp39-win_amd64.whl"
that should work…hopefully

download: dlib-19.22.99-cp39-cp39-win_amd64.whl
and download: dlib-19.22.99.win-amd64-py3.9.exe
install the .exe file on your pc, restart it(not necessary) and open the current directory of the downloaded .whl file where it is saved on your pc in your python/anaconda terminal/ cmd
for example:
C:UsersUSER->cd desktop "if you downloaded the file to your desktop" this command will move you to the current directory of the .whl file
then input: "pip install dlib-19.22.99-cp39-cp39-win_amd64.whl"
that should work…hopefully
