QUESTION
I'm following a Google Colab guide from Roboflow to train the MobileNetSSD Object detection model from Tensorflow on a custom dataset. Here is the link to the colab guide: https://colab.research.google.com/drive/1wTMIrJhYsQdq_u7ROOkf0Lu_fsX5Mu8a
The data set is the example set from the Roboflow website called "Chess sample" which everyone who registers an account on the website gets in their workspace folder. Here is the link to get that setup: https://blog.roboflow.com/getting-started-with-roboflow/
When following the Colab all steps are running completely fine until the step "Train the model". The following message is printed:
...ANSWER
Answered 2022-Apr-07 at 16:25Yes, indeed - downgrading numpy
will solve the issue - we saw this same bug in the Roboflow Faster RCNN tutorial. These new installs are now present in the MobileNet SSD Roboflow tutorial notebook.
QUESTION
I am following this tutorial to build a custom-made object detection model on Detect.
https://www.analyticsvidhya.com/blog/2021/06/simplest-way-to-do-object-detection-on-custom-datasets/
I have collected and labelled my images, put them on my Drive and I am running the following code snippet to train the model which is part of a Python Notebook on Google Colab:
...ANSWER
Answered 2022-Mar-02 at 15:07I checked the code of the core.Dataset
implementation from Detecto and I confirm what I said in my comments.
The index is created by getting all the .xml
annotation files and creating an index that maps them to their image. It does not check that the image is actually there.
For the image filename, it uses the one that is inside the xml
file, not the name of the xml
file. See below a view of an annotation XML file, where you see the filename
attribute. If you change the name of your image, you need to change it inside the xml
file.
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 want to add images without any bounding boxes to the dataset used to train an object detector using tflite model maker.
According to the docs I can add
...one row for each image with no bounding box (such as row 4 below).
ANSWER
Answered 2021-Nov-17 at 01:14Model Maker doesn't support images without any bounding boxes. Neither will the images used in the training. Thus Please avoid such data.
QUESTION
I'm trying to create my own object detection model with TensorFlow 1 in the Anaconda environment. I wanted to use TensorFlow 1.15 and I followed this tutorial https://github.com/EdjeElectronics/TensorFlow-Lite-Object-Detection-on-Android-and-Raspberry-Pi
Cuz I'm new to this I followed tutorials on how to set up TensorFlow when I reach the step on setting up TensorFlow, I used the command pip install . to install TensorFlow using the setup.py in the research directory
After the installation, I used the command to test the TensorFlow setup to verify it works:
python builders\model_builder_tf1_test.py

Now, my pip list is this.
...ANSWER
Answered 2021-Sep-07 at 09:57I have the same issue installing the Object Detection API for Tensorflow 2 (OD API) from sources on my MacBook Air M1 2020. It starts to lookup/download all available dependencies with very long errors and after several hours the process drains all available RAM and forces the laptop to reboot. I think the problem is with incompatible dependencies for arm64. I tried to build/install OD API for Tensorflow 1 instead and it worked! I successfully trained a model with TensorFlow 2 and GPU enabled.
Use the tf1
folder when you installing the OD API instead of tf2

QUESTION
I'm creating a mobile client for my object-detection server. I already have a perfectly-working python client which takes an image as input, sends it to the server in an HTTP request and receives prediction as a json response. I'm trying to achieve the same in Dart which I'm fairly new to.
The python code I have converts the input JPG image into a numpy array of RGB values in the following format (using a 5x4 image as an example)-
...ANSWER
Answered 2021-Sep-13 at 03:30Images are normally compressed when they're stored. Based on the file extension, I'm guessing you're using JPEG encoding. This means the data stored in the assets/test.jpg
file is not an array of colors. That would be an inefficient use of data storage if everything were done that way. To get that array of colors, you need to decode the image. This can be done with the image package.
To do this, first add the package as a dependency by adding the following to the pubspec.yaml

Install object-detection
You can use object-detection like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the object-detection component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
