target_size=None can not work.

[kuixu]

I found code about the input shape.

    if target_size:
        input_shape = target_size + (3,)
    else:
        input_shape = (None, None, 3)

When I set target_size=None, error encountered as below:

Traceback (most recent call last):
  File "train.py", line 132, in <module>
    data_dir, label_dir, target_size=target_size, resume_training=True)
  File "train.py", line 102, in train
    batch_size=batch_size, shuffle=True
  File "/data/kuixu/exper/fcn/Keras-FCN/utils/SegDataGenerator.py", line 186, in flow_from_directory

  File "/data/kuixu/exper/fcn/Keras-FCN/utils/SegDataGenerator.py", line 26, in __init__
    self.target_size = tuple(target_size)
TypeError: 'NoneType' object is not iterable

please help

I cannot find the line you quoted in my code:

    if target_size:
        input_shape = target_size + (3,)
    else:
        input_shape = (None, None, 3)

Can you point me to the right direction?
