QUESTION
I am following this tutorial https://github.com/EdjeElectronics/TensorFlow-Object-Detection-API-Tutorial-Train-Multiple-Objects-Windows-10.
System - Windows 10, Anaconda Prompt, Python 3.6, tensorflow 1.15.0
Initial setup and training are successful. Upon pausing the training and resuming I get the error message from the title. Any help would be greatly appreciated.
...ANSWER
Answered 2022-Feb-13 at 12:52I realized that every time I reenter the environment from the anaconda prompt I should reset the python path. This solved the problem:
set PYTHONPATH=C:\tensorflow1\models;C:\tensorflow1\models\research;C:\tensorflow1\models\research\slim
QUESTION
I'm trying debug my trained Faster R-CNN model using Tensorflow Object Detection API and I want to visualize the proposal regions of RPN on an image. Can anyone tell me how to do it?
I found a post here but it hasn't been answered. I tried to export the model using exporter_main_v2.py
with only the RPN head as said here and this is the massage when I deleted the second_stage.
ANSWER
Answered 2021-Aug-03 at 09:42Found the solution!
In the config file add number_of_stages: 1
Instead of using exporter_main_v2.py
I write code that builds the model from the checkpoint file

ANSWER
Answered 2021-May-28 at 14:40I managed to resolve by downgrading Pillow to 7.0.0, downgrading numpy to 1.19.5 (which is the latest version still compatible with tensorflow 2.5.0 at the moment) and downgrading pycocotools to 2.0.0.
QUESTION
I followed the "Training Custom Object Detector" tutorial (https://tensorflow-object-detection-api-tutorial.readthedocs.io/en/latest/training.html)
When running the script to continue training a pre-trained model:
python model_main_tf2.py --model_dir=models/my_ssd_resnet50_v1_fpn --pipeline_config_path=models/my_ssd_resnet50_v1_fpn/pipeline.config
(found here: https://github.com/tensorflow/models/blob/master/research/object_detection/model_main_tf2.py)
Using different numpy versions, I get the following errors.
Scenario #1:
- tensorflow: 2.2.0
- numpy: 1.20.0-1
NotImplementedError: Cannot convert a symbolic Tensor (cond_2/strided_slice:0) to a numpy array. This error may indicate that you're trying to pass a Tensor to a NumPy call, which is not supported
I looked online and it suggests to downgrade the numpy version < 1.20.0 (NotImplementedError: Cannot convert a symbolic Tensor (2nd_target:0) to a numpy array). Note, the version numpy version must be >= 1.19.2 for tensorflow 2.2.0.
Scenario #2:
- tensorflow: 2.2.0
- numpy: 1.19.2-5
ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 88 from C header, got 80 from PyObject
However, the online recommendation is to upgrade numpy to >= 1.20.0. (ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 88 from C header, got 80 from PyObject). There is a github issue related to this: https://github.com/tensorflow/models/issues/9749.
I'm not sure what version to use to get the code running.

pip uninstall pycocotools
pip install pycocotools-windows
QUESTION
I am trying to install Tensor Flow Object Detection on Windows 10.
After running these steps, we are receiving the errors below. It is stalling on pyarrow. How can this be fixed?
...ANSWER
Answered 2021-Apr-26 at 00:11I'm not exactly sure about that error, but for Tensorflow in general, if you go to this page, you'll see that, as of this writing, the only supported version of python are 3.6 - 3.8. It sounds like for tensorflow/models, you might do well to use 3.7. You will want to make sure you have a compatible version of pip as well.

QUESTION
For utilizing Tensorflow's Object Detection transfer learning capabilities, I followed the "Training Custom Object Detector" tutorial (https://tensorflow-object-detection-api-tutorial.readthedocs.io/en/latest/training.html)

QUESTION
The accepted answer of this question says how tensorflow draws the bounding boxes of the detected object however does not show or explain how to retrieve these coordinates. Could someone show me how this can be done for tensorflow 2?
...ANSWER
Answered 2021-Apr-01 at 01:26You can use most of the code in this documentation here.
Just add the below code for getting the bounding box coordinates (after detection_classes
has been defined)
