我正在尝试测试视频智能 API 并进行标签分析。

video_client = (video_intelligence_service_client.

features = [enums.Feature.LABEL_DETECTION]
with io.open(path, "rb") as movie:
content_base64 = base64.b64encode(movie.read())
operation = video_client.annotate_video(
'', features, input_content=content_base64)
print('\nProcessing video for label annotations:')
while not operation.done():
sys.stdout.write('.')
sys.stdout.flush()
time.sleep(15)
print('\nFinished processing.')
# first result is retrieved because a single video was processed
results = operation.result().annotation_results[0]
for i, label in enumerate(results.label_annotations):
print('Label description: {}'.format(label.description))
print('Locations:')
for l, location in enumerate(label.locations):
positions = 'Entire video'
if (location.segment.start_time_offset != -1 or

parser = argparse.ArgumentParser(

parser.add_argument('path', help='GCS file path for label detection.')
args = parser.parse_args()
analyze_labels_file(args.path)
# [END running_app]

然后我从终端 python labels.py MP4_FILE_PATH 运行它
过了一会儿,它失败了这个错误代码:

请帮助为什么它不起作用!:(
