Waiting for new Checkpoint

Can someone help me with this error. Using tensorflow2 with ssd_mobnetv2_fpnlite. My model is training properly but not evaluating. This is the code which I used to evaluate. python models/research/object_detection/model_main_tf2.py --model_dir=workspace/models/my-ssd-mobnet --pipeline_config_path=workspace/models/my-ssd-mobnet/pipeline.config --checkpoint_dir=workspace/models/my_ssd_mobnet

And below is the error

INFO:tensorflow:Waiting for new checkpoint at workspace/models/my_ssd_mobnet I0204 20:39:07.310064 140134949881664 checkpoint_utils.py:140] Waiting for new checkpoint at workspace/models/my_ssd_mobnet.

I have also run train and evaluation command simultaneously but still it gives me this error.
These are the following tutorials I have followed.
https://medium.com/swlh/guide-to-tensorflow-object-detection-tensorflow-2-e55ba3cdbc03
https://github.com/nicknochnack/TFODCourse

please do guide. These both tutorials evaluate there models by this code.
python models/research/object_detection/model_main_tf2.py --model_dir=workspace/models/my-ssd-mobnet --pipeline_config_path=workspace/models/my-ssd-mobnet/pipeline.config --checkpoint_dir=workspace/models/my_ssd_mobnet

But mine gets stuck with the message I have mentioned above.
