Reshape Error

[akshaydp1995]

I've followed exactly that's been provided:

%matplotlib inline

import os

from matplotlib import pyplot as plt
import matplotlib.pylab as pylab

from mlearning.mlearning import util
from mlearning.mlearning.coco import Annotation
from mlearning.mlearning.plotting import plot_bboxes_and_masks

pylab.rcParams['figure.figsize'] = 12, 12

ann = Annotation(path=os.path.join(os.path.expanduser('~'), 'Documents/DAS/train_ann'))

plot_bboxes_and_masks(ann)
