Issue with Ensemble model.

See original GitHub issue

When I want to use Ensemble model, like the tutorial"

resp_obj = DeepFace.verify("img1.jpg", "img2.jpg", model_name = "Ensemble")

I get the following error: There is an error with this image and modelCould not open /usr/local/lib/python3.6/dist-packages/deepface/models/face-recognition-ensemble-model.txt

How we can solve that?

the library version is 0.0.31

Let me explain the problem, maybe this helps some people having same trouble

Firstly, ensemble model needs .txt file and I stored in the repo: https://github.com/serengil/deepface/tree/master/deepface/models

Even though this text file exists in the repo, this won’t be uploaded to PyPI. Before 0.0.32, this does not exist in the repo.

Then, I found that if you add this text file as script in setup.py, then this will be uploaded to pypi.

scripts=['deepface/models/face-recognition-ensemble-model.txt'],

Even though this is uploaded to pypi, this won’t be copied when you call pip install command. That’s why, I downloaded this text file externally in the code.

DeepFace.py

home = str(Path.home())
				
if os.path.isfile(home+'/.deepface/weights/face-recognition-ensemble-model.txt') != True:
	print("face-recognition-ensemble-model.txt will be downloaded...")
	url = 'https://raw.githubusercontent.com/serengil/deepface/master/deepface/models/face-recognition-ensemble-model.txt'
	output = home+'/.deepface/weights/face-recognition-ensemble-model.txt'
	gdown.download(url, output, quiet=False)

ensemble_model_path = home+'/.deepface/weights/face-recognition-ensemble-model.txt'

deepface_ensemble = lgb.Booster(model_file = ensemble_model_path)

Funnily, this text file will be downloaded from GitHub repo 😃
