来自对象检测API的create_coco_tf_record.py未创建tfrecord文件

问题描述

我正在尝试以可可格式（.record）创建tfrecord（.json）文件。因此，我正在使用来自对象检测api github存储库的create_coco_tf_record.py脚本的this稍微修改过的版本。
我在colab上运行我的笔记本。以下是几行代码：

#Mount Google Drive.
from google.colab import drive
drive.mount('/content/gdrive') <br>

!pip install -U --pre tensorflow=="2.2.0"

#Download TensorFlow Model Garden.
import os
import pathlib
#cd into the TensorFlow directory in your Google Drive
%cd '/content/gdrive/My Drive/TensorFlow'
# Clone the tensorflow models repository if it doesn't already exist
if "models" in pathlib.Path.cwd().parts:
  while "models" in pathlib.Path.cwd().parts:
    os.chdir('..')
elif not pathlib.Path('models').exists():
  !git clone --depth 1 https://github.com/tensorflow/models

# Install the Object Detection API
%%bash
cd '/content/gdrive/My Drive/TensorFlow/models/research/'
protoc object_detection/protos/*.proto --python_out=.
cp object_detection/packages/tf2/setup.py .
python -m pip install .

#run model builder test
!python '/content/gdrive/My Drive/TensorFlow/models/research/object_detection/builders/model_builder_tf2_test.py'

!wget https://raw.githubusercontent.com/TannerGilbert/Tensorflow-Object-Detection-API-train-custom-Mask-R-CNN-model/master/create_coco_tf_record.py

# create tf record
!python create_coco_tf_record.py \
  --logtostderr \
  --train_image_dir='/content/gdrive/My Drive/TensorFlow/workspace/training_demo/images/combined/' \
  --test_image_dir='/content/gdrive/My Drive/TensorFlow/workspace/training_demo/images/combined/' \
  --train_annotations_file='/content/gdrive/My Drive/TensorFlow/workspace/training_demo/images/train_coco.json' \
  --test_annotations_file='/content/gdrive/My Drive/TensorFlow/workspace/training_demo/images/test_coco.json' \
  --output='/content/gdrive/My Drive/TensorFlow/workspace/training_demo/annotations/'

create_coco_tf_record.py脚本运行正常，没有任何错误。它显示了以下内容：

它会以某种方式不创建任何.record文件。

有人知道问题可能在这里吗？

谢谢！
