Try to input a dictionary instead of an integer into RCNN, e.g. model = keras_rcnn.models.RCNN((224, 224, 3), ["circle", "rectangle", "triangle"])

Closing. @jmd9019 Let me know if @jhung0's comment did not resolve your issue.

I also apologize for the API instability. @jhung0 and I are in the process of (semi-) stabilizing the object detection API. I'll also look at stabilizing the image segmentation API soon.

@0x00b1 @jhung0 comment did not work still facing the same issue.

One more question is this issue is because of I am running on aws ec2 instance in jupyter??

[jhung0]

No, that's not an issue. Do you have everything updated? Have you tried what's in the readme?

[jmd9019]

Yes everything is updated but haven't tried as given in readme. And I tried in Kaggle there was no issue. But I am getting this error when running on aws so i asked the above question

[jhung0]

Is it really the same error? If you input a dictionary, I'm not sure why it would give you TypeError: object of type 'int' has no len()

[jmd9019]

No getting different error now

codes:

import keras from keras.layers import Input from keras_rcnn.models import RCNN

img_in = Input((None, None, 3)) rcnn_model = RCNN((225,225, 2),["circle", "rectangle", "triangle"]) optimizer = keras.optimizers.Adam(0.0001) rcnn_model.compile(optimizer) print('Input:', rcnn_model.get_input_shape_at(0)) print('Output:', rcnn_model.get_output_shape_at(0))

Error:
