Text Detection using Neural Networks | OPENCV Python
Why Stack Overflow recommends it
Stack Overflow users link it as the tutorial they are following when they hit errors in the training or pickle-loading code, and as a model for simple digit recognition.

What it is
A feature-length tutorial by Murtaza Hassan that builds a convolutional neural network in Python with Keras and OpenCV to classify handwritten digits 0 to 9. It covers writing the training code from scratch on about 10,000 images, then a webcam script for live digit recognition.

These numbers are changing also there colors change and the background color too, must be a simpler way to recognize what numbers appeare on the screen like this tutorial : [this video]

I'm following a tutorial on YouTube ( [this video] ), the code can be found here: [LINK] But when I try to run the code below, I get the error: TypeError: only integer scalar arrays can be converted to a scalar index. x_train = np.array(list(map(preprocess, x_train))) x_test = np.array(list(map(preprocess, x_test))) x_validation = np.array(list(map(preprocess, x_validation))) x_train = x_train.reshape(x_train[0], x_train[1], x_train[2], 1) x_test = x_test.reshape(x_test[0], x_test[1], x_test[2], 1) x_validation = x_validation.reshape(x_validation[0], x_validation[1], x_validation[2], 1) I found this ( TypeError: only integer scalar arrays can be converted to a scalar index , while trying kfold cv

I am currently working on a project in which I need to use Keras pickle to detect text then I need to run yolov3 object detection. I am using Keras according to this tutorial [this video] . and I am trying to apply Yolov3 using TensorFlow according to the following tutorial. [LINK] The workflow of code is: first using Keras then yolo, and both of them are separated functions. So if I try to run my code on GPU it seems like I can't run the yolo function after running the Keras function, I keep getting this error : Physical devices cannot be modified after being initialized") RuntimeError: Physical devices cannot be modified after being initialized I had searched on the internet about how to force

I'm doing my code exactly the same with [this video] in minute 1:11:09. I write this code : pickle_in = open("venv/model_trained.p","rb") model = pickle.load(pickle_in) It showed an error like this when I tried to run it. Error that I got after running the code [LINK] Is someone having the same issue as me? Thank you. Best Regards, Bhetrand
