Problem with AttributeError: 'str' object has no attribute 'shape'

[saylideshmukh]

My text file is gt.txt where the rows are like this 00000.ppm;774;411;815;446;11

When I run this command
train_rpn.py' --network resnet50 -o simple -p D:\project\rpntrainann\gt.txt

It creates the model but then I get this error:
Traceback (most recent call last):
File "train_rpn.py", line 243, in
steps_per_epoch=10, validation_steps=100)
AttributeError: 'str' object has no attribute 'shape'

I tried different solutions but I am unable to resolve

Having the same issue, using TF 2.4.1 and Keras 2.4.3.

I did replace "K.image_dim_ordering" with "K.image_data_format"

issue is in "data_adapter.py", line 794, in _get_dynamic_shape"

printing "t" variable before it fails shows t = "aeroplane"

Any clue ?

P.S.: I understand TF and K do not match original version but I would like to see if I can run it with newer versions.

Thanks
