Cannot interpret feed_dict key as Tensor in face.py
Closed this issue · 1 comments
I run faces.py script in docker container with Ubuntu 16.04 xenial. When using the 2nd query for image classification I get internal server error with the error traceback below.

What it can be and how I can fix this? Help please to solve this issue. By the way it happens only on linux ubuntu, on my MacOS all works great
Updated:
I have tried to build Dockerfile that was in the root folder (with Debian image), nothing has been changed or added.
Commands
docker build -t face .
docker run -td face
docker exec -ti CONTAINER ID bash
curl -v -F image=@90.jpg http://localhost:8084/classifyImage > image.png
So, the output is the same, after 2 query on Flask /classifyImage API I get the Error described above
But the funny story is when I tried download image docker pull ekholabs/face-classifier and test this image --> all worked correctly!
I believe that the problem is inside installed packaged, something has been changed but I couldn't find what package is exactly differs from what had been used during the building image so times before
I found what was wrong. Package version of Flask has to be hardcoded == 0.12.2
