io issue, could not open the image.

[ZuowenWang0000]

Hello,
When I use LandmarkImg, neither operating on a single image from the samples folder nor sequence or images work. I got

Error: Could not open the image: ../samples/sample1.jpg

I don't know what to do with it since other functions work perfectly for videos. The error message is from OpenFace//lib/local/Utilities/src/ImageCapture.cpp

Another issue is I got this Could not find the HAAR face detector location both in video mode or image mode. But seems it doesn't affect the usage of video mode. But should this HAAR face detector being used heavily as the first step to detect the location of faces?

following are the error messages executing LandmarkImg. My environment is Ubuntu 16.04.
Thanks a lot!

Hi,

It should not be related to the HAAR face detector, as it is not used by default. As video processing is working, I'm wondering if you are missing certain libraries in OpenCV for decoding images, as OpenCV is used to open the images. Can you try using -f flag directly to open different format images, e.g. .png or .bmp?

ERROR: Could not load the landmark detector

when i am loading to image , i got this error on ubuntu 16.04

[TadasBaltrusaitis]

Hi,

Did you follow that link and download the required models?

[butub1]

HI, i just got the same problem using both the .png format and jpeg/jpg format image,
Have you solved this problem yet?

and i have followed that link ,and download the required models ,

on ubuntu 16.04 , g++-4.9.3 opencv-3.4.0 boost-1.69

[TadasBaltrusaitis]

Does opening videos or a webcam work for you?

[karllacr]

FaceLandmarkVid worked for me, both in the case of videos contained in the directory and on the webcam. But in FaceLandmarkImg it gives the same error:
Error: could not open the image: ../samples/sample1.jpg

being the same error for all images. I even tried with other images that I put in the directory, but it did not worked. I checked the OpenCV library and everything is fine in it.

[seunghakbae]

I have same issue as well. Everything works fine except the FaceLandmarkImg. Did anybody find a solution to it? I tried with different images and it did not work.

[TadasBaltrusaitis]

That's quite strange and I can't reproduce the error. Does FeatureExtraction executable work? It can be used for processing images, FaceLandmarkImg is only intended for visualization of results. They both use the same way of opening images.

What are the exact command line arguments you are using?

[duckyngo]

I used the command in the Unix install guide and had the same problem.

The command is : ./bin/FaceLandmarkImg -fdir "../samples/" -wild
or ./bin/FaceLandmarkImg -f "../samples/sample1.jpg" -wild

Both of them give the same error:
Model loaded Reading the AU analysis module from: ./bin/AU_predictors/main_static_svms.txt Reading the AU predictors from: ./bin/AU_predictors/AU_all_static.txt... Done Reading the PDM from: ./bin/AU_predictors/In-the-wild_aligned_PDM_68.txt... Done Reading the triangulation from:./bin/AU_predictors/tris_68_full.txt...

It worked well on the Video. I also try to test with the FeatureExraction with the command:
./bin/FeatureExtraction -f "../samples/sample2.jpg"
It worked well too.

[TadasBaltrusaitis]

Could it be something with the image itself? You tried FeatureExtraction with sample2 but FaceLandmarkImg with sample1. Could you try both with both to see if this is causing the error.

[duckyngo]

Thank for your quick response!.
I try both of them:
/bin/FaceLandmarkImg -f "../samples/sample2.jpg" -wild: the same issue occurred

./bin/FeatureExtraction -f "../samples/sample1.jpg" : It work normally

[TadasBaltrusaitis]

This seems like the problem is with the image loading library. FeatureExtraction using video loading library from OpenCV, while FaceLandmarkImg uses the image loading (imread). Possible that the dependencies for OpenCV were not installed or for some reason OpenCV cannot find them. Can you try reinstalling OpenCV?

[TadasBaltrusaitis]

Have you managed resolving the issue?

Hi

Running on Ubuntu -

Don't Have sudo or any executable access

The only way to install is conda env.

Have put the model files in right folders.

Since I don't have Executable info -
I got below instructions from others -

OpenFace Installation Steps.
The installation consists of OpenBlas, OpenCV, dlib, gcc and finally OpenFace installation
1.Follow instructions on https://github.com/TadasBaltrusaitis/OpenFace/wiki/Unix-Installation
2.For OpenBlas installation follow instructions on link: https://iq.opengenus.org/install-openblas-from-source/
3.Set correct path in file: FindOpenBLAS.cmake
4.Set correct path in file: OpenCVConfig.cmake during OpenCV installation
5.Set correct path in file OpenCVConfig-version.cmake
6.Set correct paths in cmake files and all other files in dlib, OpenCV, OpenBlas on the go, as error occurs.
7.In case of mpfr error check mpfr path using below command.
ldd /usr/libexec/gcc/x86_64-pc-linux-gnu/7.3.0/cc1 | grep mpfr

8.Create soft link on libmpfr.so using command ln –s in case of mpfr error.
9.Since, gcc 8 is required and it is not available without sudo permission, install gcc 7 using following command. Gcc of lower version doesn’t work.
conda install -c creditx gcc-7

WANTED TO KNOW STEP 3, 4, 5. How to give the path, I mean where to give the path.

Hello, I have the same issue : VIDIOC_REQBUFS: Inappropriate ioctl for device. I have already re installed open CV. I am working on Linux, Ubuntu version 20.10.

Thanks in advance.

You can find the reference solution in #962.
