Predict Error

[ruman1609]

My code when I run model to predict causing an error

step_size = train_utils.get_step_size(test_total_item, batch_size)
pred_bboxes, pred_labels, pred_scores = frcnn_test_model.predict(test_data, steps=step_size, verbose=1)

here is the stacktrace:

    TypeError: The model has multiple outputs, so `sample_weight` should be either a list or a dict. Provided `sample_weight` type not understood: Tensor("args_2:0", shape=(None, None), dtype=int32)

as my counter step, with tensorflow 2.1, I downgrade it to 2.0. Maybe you guys have an idea to fix this in tensorflow version upper 2.0
