pipeline

I'm trying to use du command for every directory in the current one. So I'm trying to use code like this: ls | du -sb But its not working as expected. It outputs only size of current '.' directory and thats all. The same thing is with echo ls | echo Outputs empty line. Why is this happening? FatalError Using a pipe sends the output ( stdout ) of the first command, to stdin (input) of the child process (2nd command). The commands you mentioned don't take any input on stdin . This would work, for example, with cat (and by work, I mean work like cat run with no arguments, and just pass along the

I am using Pipeline from sklearn to classify text. In this example Pipeline I have a TfIDF vectorizer and some custom features wrapped with FeatureUnion and a classifier as the Pipeline steps, I then fit the training data and do the prediction: from sklearn.pipeline import FeatureUnion, Pipeline from sklearn.feature_extraction.text import TfidfVectorizer from sklearn.svm import LinearSVC X = ['I am a sentence', 'an example'] Y = [1, 2] X_dev = ['another sentence'] # load custom features and FeatureUnion with Vectorizer features = [] measure_features = MeasureFeatures() # this class includes my

A period of intense googling provided me with some examples where people use both types of operators in one code, but generally they look just like two ways of doing one thing, they even have the same name tl;dr: The defining difference is that -> pipes to the first argument while |> pipes to the last. That is: x -> f(y, z) <=> f(x, y, z) x |> f(y, z) <=> f(y, z, x) Unfortunately there are some subtleties and implications that makes this a bit more complicated and confusing in practice. Please bear with me as I try to explain the history behind it. Before the age of pipe Before there were any

I have a folder in my asset pipeline called typefaces. It works without any additions to application.rb . In the directory I have different typeface types, like .eof, .ttf, etc in folders, like this Assets Typefaces Eof ...files Ttf ...files Unless the typefaces are in Assets/typefaces they don't become part of asset pipeline. Asset pipeline doesn't go into the subdirectories. How would I have asset pipeline look beyond assets/typefaces into assets/typefaces/eof, assets/typefaces/ttf etc? In your app/assets/javascripts/application.js file, try putting: //= require_tree ../Typefaces See more:

I've fit a Pipeline object with RandomizedSearchCV pipe_sgd = Pipeline([('scl', StandardScaler()), ('clf', SGDClassifier(n_jobs=-1))]) param_dist_sgd = {'clf__loss': ['log'], 'clf__penalty': [None, 'l1', 'l2', 'elasticnet'], 'clf__alpha': np.linspace(0.15, 0.35), 'clf__n_iter': [3, 5, 7]} sgd_randomized_pipe = RandomizedSearchCV(estimator = pipe_sgd, param_distributions=param_dist_sgd, cv=3, n_iter=30, n_jobs=-1) sgd_randomized_pipe.fit(X_train, y_train) I want to access the coef_ attribute of the best_estimator_ but I'm unable to do that. I've tried accessing coef_ with the code below. sgd

Background I am working on "modernizing" a pre-existing PHP-driven website. This website started out as a static website with a few php methods. It now has a mobile web app, multiple models, and a lot of dynamic content. However, overtime the structure of the app itself hasn't changed much from when it was a largely static site, so now there are include files all over the place, no separation of application/presentation logic, etc etc. It is a mess to work on. So I am reorganizing everything and redeveloping a lot of the pre-existing functionality as we prepare for upcoming upgrades to the
