vqa.getImgIds throwing error with single int question_id

[manikandtan-ck]

from external.vqa.vqa import VQA
import os
data_dir = "../../../data/vqa/data"
annotation_json_file_path = os.path.join(data_dir, "mscoco_train2014_annotations.json")
question_json_file_path = os.path.join(data_dir, "OpenEnded_mscoco_train2014_questions.json")

vqa = VQA(annotation_json_file_path, question_json_file_path)

q_requested = vqa.loadQA(ids=[409380])
img_id_requested = vqa.getImgIds(quesIds=[q_requested[0]['question_id']])

output:
Traceback (most recent call last): File "q1.py", line 13, in <module> img_id_requested = vqa.getImgIds(quesIds=[q_requested[0]['question_id']]) File "external\vqa\vqa.py", line 113, in getImgIds anns = sum([self.qa[quesId] for quesId in quesIds if quesId in self.qa], []) TypeError: can only concatenate list (not "dict") to list

is this the expected behaviour? I modifed line 113 in vqa.py to return the image_id as below but not sure if it will break something else.

anns = [self.qa[quesId] for quesId in quesIds if quesId in self.qa]
