TypeError: deconv_length() missing 1 required positional argument: 'output_padding'.. This issue can be solved using keras=2.1.6 with python 3.6.x

If using the latest version of Keras please use output_padding=None, this seems to solve the issue

Another problem is: "Too many indices for array, skipping files " , with 10 images and mask. but when i load MSCOCO data set with 10 images and mask it working.

[Cheng-Lin-Li]

Hi hiteshnitetc,

How many channels in your mask image? It should be only one channel as gray scale images.

[hiteshnitetc]

@Cheng-Lin-Li Hello, yes my mask images are gray scale only, with channel 1, and keras is set to channel last topology

[AfsahS]

I have same issue, code works fine with MSCOCO dataset, but have same error with different datasets.

[fenaux]

Hello,
I get the same issue
My configuration is : ubuntu 18.04.2, Python 3.6.7, Keras 2.2.4

The data were obtained with
python3 getcoco17.py --data_root_dir ../data --category person --annotation_file ../data/annotations/instances_train2017.json --number 10 --id 22228 178040 167494 144599 13800 147865 279422 477861 123512 69578

And then I run
python3 ./main.py --test --Kfold 2 --net segcapsr3 --data_root_dir=data --loglevel 2 --which_gpus=-2 --gpus=0 --dataset mscoco17 --weights_path data/saved_models/segcapsr3/split-0_batch-1_shuff-1_aug-0_loss-dice_slic-1_sub--1_strid-1_lr-0.0001_recon-20.0_model_20180705-092846.hdf5

thanks for your help

Extract from
documentation of deconv_length line 148 and 149
https://github.com/keras-team/keras/blob/master/keras/utils/conv_utils.py
output_padding: Integer, amount of padding along the output dimension,
Can be set to None in which case the output length is inferred

Then I introduced the following modifications in "capsule_layers.py"
ddition on line 250 output_padding = None
New 251 (was 250) out_height = deconv_length(self.input_height, self.scaling, self.kernel_size, self.padding, output_padding)
New 252 (was 252) out_width = deconv_length(self.input_width, self.scaling, self.kernel_size, self.padding, output_padding)

addition on line 284 output_padding = None
new 285 (was 283) output_shape[1] = deconv_length(output_shape[1], self.scaling, self.kernel_size, self.padding, output_padding)
new 286 (was 284) output_shape[2] = deconv_length(output_shape[2], self.scaling, self.kernel_size, self.padding, output_padding)

and it seems it works. I get 5 output masks
But I now have an other issue : "Unable to find weights path. Testing with random weights".

[fenaux]

I found the solution :
In test.py
Line 109 weights_path = join(args.data_root_dir, args.weights_path)
then data should not be repeated in weight_path => command line modified accordingly
python3 ./main.py --test --Kfold 2 --net segcapsr3 --data_root_dir=data --loglevel 2 --which_gpus=-2 --gpus=0 --dataset mscoco17 --weights_path saved_models/segcapsr3/split-0_batch-1_shuff-1_aug-0_loss-dice_slic-1_sub--1_strid-1_lr-0.0001_recon-20.0_model_20180705-092846.hdf5

Thanku you for your detailed reply, i will try out your suggestions.

Hi fenaux,

Thanks for your findings and suggestions.
I will revise the document and code accordingly.

[tanchaozhen]

I get the same issue.
I solved the first problem "deconv_length() missing " using keras=2.1.6 with python 3.6.x.
But,"Too many indices for array, skipping files" still cannot be solved. Have you solved it?

[hiteshnitetc]
