[FasterRCNN] Checkpoint is expected to be an object-based checkpoint_Object detection.

[lacls]

Prerequisites

• I am using the model faster_rcnn_resnet101_v1_800x1333_coco17_gpu.

https://github.com/tensorflow/models/tree/master/research/object_detection

1. Describe the bug

My running on the terminal

python object_detection/model_main_tf2.py \
    --pipeline_config_path=/home/MaskRCNN_DeepFashion2/models/research/object_detection/configs/tf2/faster_rcnn_resnet101_v1_800x1333_coco17_gpu-8.config \
    --model_dir=home/MaskRCNN_DeepFashion2/Mask_RCNN/CP \
    --num_train_steps=10000 \
    --sample_1_of_n_eval_examples=1 \
    --alsologtostderr

The error I got is below

OSError: Checkpoint is expected to be an object-based checkpoint.

Here is my config file with ONLY Fine-tune part

Thanks you guys, again!
