packages

问题 When I download any package using NPM, it hangs on the last command "loadRequestedDeps." I've added my whole -verbose output to the end of this question for reference. It will just sit there until I cancel the command, and nothing will be installed and my package.json will not be updated. What could the issue be? I've looked around but haven't found out how to fix my particular problem. Here's some info: OS is Windows 10 Node version is 6.9.1 NPM version is 3.10.8 My CPU maxes out at 100%

问题 This question already has answers here : Why do java source files require package declarations? (4 answers) Closed 4 years ago . In java, why is it mandatory for each class to declare the package it belongs to. I mean, package hierachy is already described/enforced using the folder structure of the file system. It looks to me that the line: package com.mypackage; As the first line of each class is somehow a redundant information. But I'm pretty sure there's a good reason for it to be there.

问题 I have a class file in Matlab. I created i directory structure using the package specifications. +MyPkg |--+F1 |--+F2 |--+F3 | |--fun.m |--myc.m My class is myc and it is inserted in the package MyPkg . A function fun is saved in subpackage F3 in the main one. I want to use function fun in my class. How??? 回答1: You need to refer to fun as MyPkg.F3.fun everywhere. Unfortunately, full packages must be used explicitly everywhere in MATLAB (or, you must use import statements). 回答2: The way you

问题 I am writing a python module neuralnet . It was working all fine in Python2, but in Python3, imports are failing. This is my code structure. neuralnet/ __init__.py train.py # A wrapper to train (does not define new things) neuralnet.py # Defines the workhorse class neuralnet layers/ __init__.py inlayer.py # Defines input layer class hiddenlayer.py application/ # A seperate application (not part of the package) classify.py # Imports the neuralnet class from neuralnet.py train.py needs to

问题 I have been using the "stats" package in R 3.0.1 without any problems . But today i deleted the "stats" folder from the R library location and now I can't install it any more. I tried doing the same thing with other packages but I could install everything except "stats" install.packages("stats", dep = TRUE, repos="http://cran.cs.wwu.edu") ## Installing package into ‘%Default R Lib Installation Path%’ ## (as ‘lib’ is unspecified) ## Warning in install.packages : package ‘stats’ is not

问题 In one of my directories I have all .java files which belong to one package ("game"). Now I want to create one .java file which does not belong to this package and which imports the "game" package. If I create a new file and write import game; then Eclipse complains that it does not know what the "game" package means. Can somebody please help me to solve this problem? 回答1: You cannot import a package, you need to import classes from that package: import game.SomeClass; import game

问题 My project folder contains: Makefile README.md component/ driver/ service/ vendor/ worker/ I'd like to run go test on all test files, e.g. foobar_test.go files except for the test files in the vendor package. The closest I've come to success was with go test ./... but that included vendor test files. I saw in the documentation you can pass a regex to -run option but I'm having trouble getting this working. For example I tried go test ./* , but I get a bunch of can't load package errors . What

问题 I've set up my project with Visual Studio Express 2012, added some C# code, and successfully compiled/deployed to emulator. At some point I decided I want to do something with JSON, and I found that I should use the Json.NET framework, which is available as a NuGet package. I have added this framework successfully using the command Install-Package Newtonsoft.Json . I tried to install an update which MSVC offered two days ago, and the installation failed, leaving me unable to open my project

问题 I'm trying to implement the FBeta_Score() of the MLmetrics R package: FBeta_Score <- function(y_true, y_pred, positive = NULL, beta = 1) { Confusion_DF <- ConfusionDF(y_pred, y_true) if (is.null(positive) == TRUE) positive <- as.character(Confusion_DF[1,1]) Precision <- Precision(y_true, y_pred, positive) Recall <- Recall(y_true, y_pred, positive) Fbeta_Score <- (1 + beta^2) * (Precision * Recall) / (beta^2 * Precision + Recall) return(Fbeta_Score) } in the H2O distributed random forest model
