Hi Friends,
I am trying to test the implementation of character recognition using Julia in my Windows 10 machine using the tutorial from https://www.kaggle.com/c/street-view-getting-started-with-julia/data. I am trying to train my system using the sample images and the code works fine in mac and in windows machine I am facing the trouble. Below is the code which I am using to implement it. Pkg.add("Images") Pkg.add("DataFrames") using Images using DataFrames using Images.ColorTypes using FixedPointNumbers using Iterators function read_data(typeData, labelsInfo, imageSize, path) x = zeros(size(labelsInfo, 1), imageSize) if !ispath(path) error("$path is not valid") end for (index, idImage) in enumerate(labelsInfo[:ID]) nameFile = "C:\\Users\\user\\Desktop\\test \\OCR_test\\$(typeData)Resized\\$(typeData)Resized\\$(idImage).bmp" if isfile(nameFile) img = load(nameFile) temp = convert(Image{Gray}, img) x[index, :] = reshape(temp, 1, imageSize) else warn("$file does not exist") end end return x end imageSize = 400 path = "C:\\Users\\user\\Desktop\\test\\OCR_test" println(path) labelsInfoTrain = readtable("$(path)\\trainLabels.csv") xTrain = read_data("train", labelsInfoTrain, imageSize, path) yTrain = map(x -> x[1], labelsInfoTrain[:Class]) yTrain = int(yTrain) labelsInfoTest = readtable("$(path)\\sampleSubmission.csv") xTest = read_data("test", labelsInfoTest, imageSize, path) Pkg.add("DecisionTree") using DecisionTree model = build_forest(yTrain, xTrain, 20, 50, 1.0) predTest = apply_forest(model, xTest) labelsInfoTest[:Class] = char(predTest) writetable("$(path)\\juliaSubmission.csv", labelsInfoTest, header=true, separator=',') Below is the error I am getting while implementing the code julia> include("C:\\Users\\user\\Desktop\\test\\OCR_test\\Forest.jl") INFO: Nothing to be done INFO: Nothing to be done C:\Users\user\Desktop\test\OCR_test ERROR: LoadError: UndefVarError: file not defined in read_data at C:\Users\user\Desktop\test\OCR_test\Forest.jl:25 in include at boot.jl:261 in include_from_node1 at loading.jl:304 while loading C:\Users\user\Desktop\test\OCR_test\Forest.jl, in expression starting on line 43 I am new to Julia and I really appreciate any help you could provide on this Thanks & Regards
