Re-reading CSV method for bufferedSource

I'm trying to read a csv and gather two types of informations.



I need to read it once to get the number of lines that my csv contains.
I need to go back to the top of the csv and re read it again to retrieve the values.
I'm looking for something similar to seek(0) in java for bufferedSource
I've tried to close and re open the buffer but I think I'm overthiking it.
I also read through the source library but nothing came close to what I'm looking for.



PS:I know this is not optimized however my first read will basically enable me to create an array to store the values I'd retrive from the second read(and not a list).



I would take any clue you might have to offer !



Thanks a lot

  • You might start with a CSV processing library. You don't want to do this yourself.

  • Why not just .fromFile("...").getLines().toArray?

  • I will look into the option suggested above. And I must do it on my own which means no spark scala and such..

A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

Image
0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{...

Calculate evaluation metrics using cross_val_predict sklearn

Image
1 In the sklearn.model_selection.cross_val_predict page it is stated: Generate cross-validated estimates for each input data point. It is not appropriate to pass these predictions into an evaluation metric. Can someone explain what does it mean? If this gives estimate of Y (y prediction) for every Y (true Y), why can't I calculate metrics such as RMSE or coefficient of determination using these results? python scikit-learn cross-validation share | improve this question edited Nov 28 '18 at 17:52 desertnaut 20.3k 7 43 79 ...
