FailedPreconditionError

[BraveDistribution]

Loading model image and using any of the methods returns FailedPreconditionError.

FailedPreconditionError: 2 root error(s) found.
  (0) Failed precondition: Error while reading resource variable block5_conv1_2/kernel from Container: localhost. This could mean that the variable was uninitialized. Not found: Container localhost does not exist. (Could not find resource: localhost/block5_conv1_2/kernel)

My code:

model = load_model(os.getcwd() + "/models/saved_models_for_fusion/0_FusionVGGMnistToPS.h5")
img_path = str(Path(os.getcwd() + "/models/scripts/xxx.jpg"))
img = load_img(img_path)
explainer = Saliency(model, layer=3)
exp = explainer.explain(img, 0)

I think that the resolution can be found here:
tensorflow/tensorflow#28287 (comment) is it possible to check whether this can fix this issue? It seems that loading model and using model.predict() fails due to not thread-safe operations.

Thanks
