failing to install dlib on windows 10

问题

Trying to install dlib on Windows 10 using pycharm package manager. I have Numpy, opencv-python, setuptools and wheel installed. tried installing dlib then got the first error asking me to install CMake.

Now I'm getting this: (tried installing visual studio but it had no effect).

What am I missing here? I'm really baffled.

回答1:

pip install https://pypi.python.org/packages/da/06/bd3e241c4eb0a662914b3b4875fc52dd176a9db0d4a2c915ac2ad8800e9e/dlib-19.7.0-cp36-cp36m-win_amd64.whl#md5=b7330a5b2d46420343fbed5df69e6a3f

Try this cmd command, it worked for me

回答2:

I have followed below steps to install face_recognition (dlib):-

Re-installed Python 3.6.6 (https://www.python.org/ftp/python/3.6.6/python-3.6.6-amd64.exe).
pip3 install cmake
pip3 install dlib
pip3 install face_recognition

It worked for me.

回答3:

The error is telling you the answer. The CMAKE_C_COMPILER:

    cl

  is not a full path and was not found in the PATH.

  To use the NMake generator with Visual C++, cmake must be run from a shell
  that can use the compiler cl from the command line.  This environment is
  unable to invoke the cl compiler.  To fix this problem, run cmake from the
  Visual Studio Command Prompt (vcvarsall.bat)."

Try to compile using the Visual Studio command prompt. The path to it there should be correct too.

回答4:

The best method to install dlib and openCV is given here.

It simply uses pip to perform all the installations. The major things that people miss or do a mistake in for Windows are declaring the PATH variables and saving them to valid address in your pc apart from the proper version matching. The above blog clearly signifies the versions to be used and declarations of PATH variables.

Just a 3 step process:-

Install anaconda
Activate Virtual Environment
Install openCV and dlib using pip (or any other required packages)

回答5:

I know this question is for windows, But by chance if someone is looking for solution for this on Mac,

Try this command, worked for me

pip install https://files.pythonhosted.org/packages/05/57/e8a8caa3c89a27f80bc78da39c423e2553f482a3705adc619176a3a24b36/dlib-19.17.0.tar.gz#SHA256=92587c81b0165e933593f505fdf099dface0d0f8ec874b1d8655fc774598911f

回答6:

Use the following code in the terminal which is accessible through Alt+F12 on your keyboard.

pip install dlib==19.8.1

You should be good to go.
