faster_rcnn_resnet101 is not supported.

Prerequisites

Tensorflow version I am using is 1.15.2
Using google colab

When I started training, by the command
!python3 train.py --logtostderr --train_dir=../training --pipeline_config_path=../training/faster_rcnn_resnet101_coco.config

Got error
Use object_detection/model_main.py.

See model_builder.py for features extractors compatible with different versions of Tensorflow

I tried different models than and getting the same error again and again.
