Using pretrained model with keras: AttributeError: ‘NoneType’ object has no attribute ‘shape’

keras machine-learning python python-3.x tensorflow

I’m running a Keras Neural Network model for a binary classification of images. I use the first layer of a pretrained VGG16 model and i created the last fully connected layers from the tutorial: https://blog.keras.io/building-powerful-image-classification-models-using-very-little-data.html With Tensorfl…

Tensor Flow Conv1D for binary classification CNN

conv-neural-network machine-learning neural-network python tensorflow

I’m creating a Conv1D layer in a CNN for binary classification, and I’m quite new to Machine Learning and I need some help to figure out the correct values for Conv1D: I would like to know if there is a way to determine the “Right” hyper-parameters that will fit my dataset best. Answer…

ValueError: Input 0 of layer sequential is incompatible with the layer: : expected min_ndim=4, found ndim=2. Full shape received: [None, 2584]

I’m working in a project that isolate vocal parts from an audio. I’m using the DSD100 dataset, but for doing tests I’m using the DSD100subset dataset from I only use the mixtures and the vocals. I’m basing this work on this article First I process the audios to extract a spectrogram an…

Input data cannot be a list XGBoost

Here is my code. and the error I’m getting is TypeError: Input data can not be a list. The data coming from test_data is a csv with a team name and obs which is a float like this NYY 0.324 Every way to solve it I’ve seen is just to put it in a 2d array like I did –

I keep getting ValueError: Shapes (10, 1) and (10, 3) are incompatible when training my model

deep-learning machine-learning python scikit-learn tensorflow

Turning the number of inputs when I call makeModel from 3 to 1 allows the program to run without errors but no training actually happens and the accuracy doesn’t change. Answer LabelEncoder transforms the input to an array of encoded values. i.e if your input is [“paris”, “paris”…

Why is my target value not the same when I print it out and calculate it with the coefs and intercept?

machine-learning polynomials python

I have worked on a Polynomial Regression model to predict my target values. The thing is that my prediction , with the “predict” method, make sense, but when I calculate the target variable via the coefs and intercept I get a value way far from the given values of the predict method. If I calculat…
