vision_model_test_manual is for manual testing of all keras vision models.
Test will run only manually with all parameters specified manually, for example:
bazel run -c opt integrations/tensorflow/e2e/keras:vision_model_test_manual -- \
--target_backends=tf,iree_vmla,iree_llvmjit \
--data=imagenet \
--include_top=1 \
--url=https://storage.googleapis.com/iree_models/ \
--model=ResNet50

Command arguments description:
--target_backends: can be combination of these: tf,iree_vmla,iree_llvmjit
--data: can be 'imagenet' or 'cifar10'.
    imagenet - input image size (1, 224, 224, 3)
    cifar10 - input image size (1, 32, 32, 3) - it is used for quick tests
            and needs pretrained weights, we pretrained models: ResNet50, MobileNet, MobileNetV2
--include_top: can be 1 or 0. Include top layer 1, not include top layer 0
--url: we need it only for cifar10 models to load weights from https://storage.googleapis.com/iree_models/
       imagenet pretrained weights url is specified by keras
--model: supports ResNet50, MobileNet, MobileNetV2, ResNet101, ResNet152,
    ResNet50V2, ResNet101V2, ResNet152V2, VGG16, VGG19, Xception,
    InceptionV3, InceptionResNetV2, DenseNet121, DenseNet169,
    DenseNet201, NASNetMobile, NASNetLarge
    All above models works with 'imagenet' data sets.
    ResNet50, MobileNet, MobileNetV2 work with both 'imagenet' and 'cifar10' data sets.
