cannot import name 'estimator' from 'tensorflow.compat.v1'

Prerequisites

Please answer the following questions for yourself before submitting an issue.

• [ yes] I am using the latest TensorFlow Model Garden release and TensorFlow 2.
• [ Yes] I am reporting the issue to the correct repository. (Model Garden official or research directory)
• [Yes ] I checked to make sure that this issue has not been filed already.

1. The entire URL of the file you are using

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

2. Describe the bug

I am using tensorflow 2.19 and latest version of the object detection api. While training the models it raises error estimator cannot import name estimator from tensorflow.compat.v1. I found that the last support for the estimator from tensorflow.comapt.v1 was in tensorflow==2.15. I tried downgrading to 2.15 which solves this issue but raises other issues.

3. Steps to reproduce

command = [
"python", "models/research/object_detection/model_main_tf2.py",
f"--model_dir={checkpoint_path}",
f"--pipeline_config_path={pipeline_config_path}",
"--num_train_steps=10000",
"--sample_1_of_n_eval_examples=1",
"--alsologtostderr"
]

process = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.STDOUT, text=True)

4. Expected behavior

It should have trained the model without raising error.

5. Additional context

6. System information

• OS Platform and Distribution (e.g., Linux Ubuntu 16.04):
• Mobile device name if the issue happens on a mobile device:
• TensorFlow installed from (source or binary):
• TensorFlow version (use command below):
• Python version:
• Bazel version (if compiling from source):
• GCC/Compiler version (if compiling from source):
• CUDA/cuDNN version:
• GPU model and memory:

Start with research/object_detection/inputs.py and the import traceback, then run models/research/object_detection/model_main_tf2.py with the reported pipeline and checkpoint arguments under TensorFlow 2.19. Check how the TensorFlow estimator dependency is handled and verify that training starts without the ImportError.
