Get ERROR msg "'unicode' object is not callable" when I implement my test script.

Hello, I'm new to tensorflow keras api and 3d object detection.
When I call tf.keras.models.load_model() func after training the model, got the following error msg which make me confusion:

Traceback (most recent call last):
  File "/home/xxx/tensorflow/PointPillars-master/test.py", line 24, in <module>

In File "/home/xxx/tensorflow/PointPillars-master/network.py", there are these codes around line 33:

    if batch_size > 1:
        corrected_indices = tf.keras.layers.Lambda(lambda t: correct_batch_indices(t, batch_size))(input_indices)
    else:
        corrected_indices = input_indices

Same problem.

corrected_indices = tf.keras.layers.Lambda(lambda t: correct_batch_indices(t, batch_size))(int(input_indices)) TypeError: 'str' object is not callable

@in4ight @sivaprasadraju could you share your test script ? thanks a lot, my mail is [email protected]

Same problem. @in4ight @sivaprasadraju Has your problem been solved？ And if so, could you share the solution? Thanks very much.

@sivaprasadraju Bro did you solved the problem,and i have downloaded the log file (from drive)how to see the output after feeding the testing folder please help,what is the code?????
