IOError: [Errno 21] Is a directory: 'data0/.ipynb_checkpoints'

[Hemanth-Mydugolam]

can anybody help ton this issue please.
while calling the function in the python code as:
cat_counter = get_car_categories()

the called function definition is as follows:

def get_car_categories():
d = defaultdict(float)
img_list = os.listdir('data0')
for i, img_path in enumerate(img_list):
path = 'data0/'+img_path
img = prepare_image(path)
out = vgg16.predict(img)
top = get_predictions(out, top=5)
for j in top[0]:
d[j[0:2]] += j[2]
if i % 50 == 0:
print i, '/', len(img_list), 'complete'
return Counter(d)

I am getting error as follows:
