I am trying to create a convolutional neural network to classify MNIST data with Flux in Julia. I downloaded the data as a csv from this link: MNIST in CSV | Kaggle . My code is below: using CSV using DataFrames using Images using Base.Iterators: partition using Flux sqrt(x) = convert(Int64, floor…

Why is there a "Warning: Slow Fallback implementation" and a DimensionMismatch error?

Your train_X and test_X have element type Any. Choose something concrete.
