Unable to run the code

[dmardanbeigi]

I downloaded the code and I'm trying to run the code using python main.py test ./sample_image but I get the following error. I tried with both pretrained models and I get the same error. I'm using python3.6, theano 0.9.0, and keras 2.0.4.

Hi @dmardanbeigi, thanks for downloading our code!

You have to use Keras 1.1.0. Unfortunately, this code is not compatible with Keras 2.

Thanks Marcella, I downgraded the Keras to version 1.1.0. No I get a different error whenI run the code (see the log below). I’m not sure if I need to download an older version of theano as well?

here is the error I get:

It seems that you are not loading the input images correctly. Try to add a slash at the end of your path. Your path should become "/SaliencyMap/mlnet-master/sample_images/".

Thanks. Now it's working.
