invalid index to scalar variable with batch each[2]
Code is shown as follow. It keep shows invalid index to scalar variable. still don't know the reason.
The problem is shown on line 90
batch = each[2][i:i + batch_size]
which cause the problem. IndexError: invalid index to scalar variable.
Full code for the function is shown as below:
def predict_on_frames(frames_folder, model_file, input_layer, output_layer, batch_size):
input_height = 299
input_width = 299
input_mean = 0
input_std = 255
batch_size = batch_size
graph = load_graph(model_file)
labels_in_dir = os.listdir(frames_folder)
frames = [each for each in os.walk(frames_folder) if os.path.basename(each[0]) in labels_in_dir]
predictions =
for each in frames:
label = each[0]
print("Predicting on frame of %sn" % (label))
for i in tqdm(range(0, len(each[2]), batch_size), ascii=True):
batch = each[2][i:i + batch_size]
try:
batch = [os.path.join(label, frame) for frame in batch]
frames_tensors = read_tensor_from_image_file(batch, input_height=input_height, input_width=input_width, input_mean=input_mean, input_std=input_std)
pred = predict(graph, frames_tensors, input_layer, output_layer)
pred = [[each.tolist(), os.path.basename(label)] for each in pred]
predictions.extend(pred)
except KeyboardInterrupt:
print("You quit with ctrl+c")
sys.exit()
except Exception as e:
print("Error making prediction: %s" % (e))
x = input("nDo You Want to continue on other samples: y/n")
if x.lower() == 'y':
continue
else:
sys.exit()
return predictions
