Error while installing dlib

[saimj7]

Hi, you need to install CMake and add its directory to the path environment variable: https://cmake.org/install/

@saimj7 While running on input video, I am getting this error. And it works fine with laptop webcam.
Kindly, look into this and let me know.
Thanks in advance.

Can you install the requirements as in requirements.txt?

[vamsireddy22]

version of opencv-python is 4.5.2.52

but while trying to install version of 4.2.0.32 it results in error! refer below picture

Weird, I'm able to install it again, are you using anaconda? What is your python version?

[vamsireddy22]

Yes :( Initially I tried using cmd, but I got errors then I tried in Anaconda. Kindly help me na!

[vamsireddy22]

Yes, now I installed all requirements as per requirements file but I am got this error while running on video input.
P.S: Running using cmd
Python version 3.7.4

C:\Users\BHEEMIREDDY VAMSI\Desktop\Main-Project>python run.py --prototxt mobilenet_ssd/MobileNetSSD_deploy.prototxt --model mobilenet_ssd/MobileNetSSD_deploy.caffemodel --input videos/example_01.mp4

Let's try to break it down, did you install ffmpeg (add its directory to the path environment variable) on windows? Also, did you build OpenCV from scratch?

[vamsireddy22]

1. I installed ffmpeg using this command pip install python-ffmpeg
2. No, I did not build the OpenCV from scratch

[saimj7]

Download ffmpeg https://ffmpeg.org/download.html and add its directory to the path.

[vamsireddy22]

Done Installed ffmpeg and added to environmental variables.
P.S : Again same error.

[saimj7]

Can you install python and the requirements using anaconda? (make sure to use anaconda prompt instead of cmd) E.g., https://medium.com/@GalarnykMichael/install-python-anaconda-on-windows-2020-f8e188f9a63d

[vamsireddy22]

Yes, bro. Did that. Let me summarize what I did so far!

1. Tried in cmd with python version 3.7.4, installed all requirements.
2. Tried in anaconda with python version 3.7.4, installed all requirements.

PS : It is working fine for Webcam.

[saimj7]

Can you try this in anaconda? Create a new environment, do conda install pip and then: pip install dlib==19.22.0 imutils==0.5.4 numpy==1.20.3 opencv-python==4.5.2.52 schedule==0.6.0 scipy==1.6.3. Python version would be 3.9.5 by default. I am trying to check if you have the file opencv_videoio_ffmpeg452_64.dll in your anaconda environment path (by default something like C:\Users\xxx\Anaconda3\envs\test\Lib\site-packages\cv2).

[vamsireddy22]

Sir, I did everything. In last conversation you said building the opencv from scratch. How can I do that?

I tried above packages installation on both cmd and anaconda. Got the same error. Something with my OpenCv tobe specific while extracting the patterns. Kindly, go through the below error.

[saimj7]

Did you create a new Conda environment and do you find the file opencv_videoio_ffmpeg452_64.dll?

[vamsireddy22]

No, sir. I couldn't found any such file. How can do it.?

[saimj7]

Can I test this myself? Please email me.
