2. Describe the bug

Whenever I run the file I get the following error:

2024-02-13 17:26:05.504018: I tensorflow/core/util/port.cc:113] oneDNN custom operations are on. You may see slightly different numerical results due to floating-point round-off errors from different computation orders. To turn them off, set the environment variable `TF_ENABLE_ONEDNN_OPTS=0`.

3. Steps to reproduce

Clone the repo and run the file

4. Expected behavior

The file should run the tests without any errors

5. Additional context

This has been happening for a while with the file: https://github.com/tensorflow/models/blob/master/research/object_detection/model_main_tf2.py
I reinstalled everything and ran the file in a virtual environment to see if it fixed itself and it didn't. This error happens with both the est file and the normal file.

6. System information

• Windows 10 22H2 19045.3930
• Mobile device name if the issue happens on a mobile device:
• TensorFlow installed from binary
• TensorFlow version (use command below): 2.15.0
• Python version: 3.9.1
• Bazel version (if compiling from source):
• GCC/Compiler version (if compiling from source):
• CUDA/cuDNN version: Not using
• GPU model and memory: Not using

Hi @RodasPneus ,

Thanks for reaching out here, but it is happening with research repository code as it is not having much development now a days.
I strongly suggest utilizing the TensorFlow Official Model Garden to circumvent issues related to outdated code commonly found in research codebases. Unlike the research repositories, the Official Model Garden is consistently updated and aligned with the latest changes in TensorFlow and other libraries and there are lot of API's are available that you can define a training experiment using Python commands in the TensorFlow Model library.

Thank you for answering, do you think that downgrading tensorflow would work?

[laxmareddyp]

Hi @RodasPneus ,

I am not sure whether it works are not since the research code base is not aligned with the latest changes in TF Framework and there are few libraries deprecated time to time with the new releases in TF.But I suggest you try with downgrading Tensorflow and see if it works. I would like you to move on to official Model Garden repo to work with latest changes in your code.

Thanks.

I'm sorry to bother you again, I managed to fix the previous issue by downgrading tensorflow to 2.5.0, and by changing some stuff inside of the object_detection library to be able to use tf.contrib.slim, however the following lines

from object_detection.meta_architectures import deepmac_meta_arch
from object_detection.models import center_net_hourglass_feature_extractor
from object_detection.models.keras_models import hourglass_network
from object_detection.protos import center_net_pb2
from object_detection.protos import model_pb2
from object_detection.utils import tf_version

Now give me errors like this

    from object_detection.meta_architectures import deepmac_meta_arch
ImportError: cannot import name 'deepmac_meta_arch' from 'object_detection.meta_architectures' (C:\Users\rodri\AppData\Local\Programs\Python\Python39\lib\site-packages\object_detection\meta_architectures\__init__.py)

Do you have any idea on how to solve this?

Hi @RodasPneus ,

No, not at all, Happy to help you.!

It seems like there might be compatibility issues or changes in the object detection library you're using.Make sure that the object detection library is correctly installed in your environment. Sometimes, incomplete installations(since you are downgrading the TF version) or corruption during installation can lead to such errors.Also i suggest you to try with TF2.6.0 version to see if this error disappears.

But working with old Versions of TF would lead to these kind of errors due to deprecation the libraries or renaming the libraries.

Thanks
