[ERROR] StopIteration: index 117 is out of bounds for axis 1 with size 66

[MathiasGilson]

Hi,
I tried to run the model but I get the following error

Epoch 1/100
Traceback (most recent call last):
File "/home/user/.local/lib/python3.5/site-packages/keras/utils/data_utils.py", line 578, in get

categorical[np.arange(n), y] = 1
IndexError: index 117 is out of bounds for axis 1 with size 66

The above exception was the direct cause of the following exception:

Traceback`(most recent call last):
File "train", line 63, in

StopIteration: index 117 is out of bounds for axis 1 with size 66

Any ideas ?

Many thanks

Labels need to be in greyscale like in the mapillary dataset

Aslo have index 117 is out of bounds for axis 1 with size 66

I just downloaded research sample :
https://s3-eu-west-1.amazonaws.com/static.mapillary.com/MVD_research_samples.zip

Can it be used to check things work?

Masks look like they are in color, should they be converted to other format?

Also where is to find config?

Keras-ICNet/test

Line 50 in c518e29

with open('datasets/mapillary/config.json') as config_file:

The samples are not in the same format as the full dataset, you should request for the whole dataset on the website https://www.mapillary.com/dataset/vistas
I personally set classes for my labelled images myself
