问题 I'm starting to learn python. So the first thing I did was install python, in this case ubuntu 16.04 LTS, since in this system python is already installed. As a first test, I tried to run a simple program with numpy library, but program n does not run, it displays the following error: import sitecustomize' failed; use -v for traceback <type 'numpy.ndarray'> It seems to me that Spyder failed to import the numpy library, although I've already called it by the terminal and it came, that is, it's

问题 I'm having trouble installing tidyverse in R. When installing the package, the installation starts but stops after a while and nothing happens. It seems like it's still in "installation mode" since I cannot to anything else (when I try to create a variable, it doesn't show up in the global environment/nothing happens). What am I doing wrong? 回答1: It must be an internet connection error. Trying installing it in this way: install.packages("devtools") devtools::install_github("hadley/tidyverse")

问题 Assume an R package ( myPackage ) that imports the R package RCircos via the DESCRIPTION file and the NAMESPACE file. $ cat DESCRIPTION Package: myPackage Imports: RCircos (>= 1.2.0) ... $ cat NAMESPACE import(RCircos) ... One of the perks of RCircos is that it defines a custom environment (called RCircos.Env ) and reads/writes variables to this environment from various of its functions. For example, function RCircos.Initialize.Plot.Parameters reads and writes to this environment. ...

问题 When I use IDLE the code "import statistics" runs, however when I use sublimetext while other packages, such as matplotlib, can be imported I cannot import the statistics module. It gives me this error code: import math import matplotlib import statistics I expect nothing to happen on the screen, but in the command line it spits out. Note that the first two lines of code did work. ImportError: No module named statistics [Finished in 1.2s with exit code 1] [shell_cmd: python -u "/Users/Ivan

问题 I'm having trouble importing packages into package objects. It didn't seem to work in Eclipse and so I switched to intellij. At one point the feature seemed to be working and so I created package objects for most packages. Now it doesn't seem to be working at all. Here's a package object in file package.scala, the package file itself compiles fine: package rStrat.rSwing package testSw //Edited for clarity object testSw { import rStrat._ import rSwing.topUI._ } and here's a class file from the

问题 Is there any way to encrypt the SQL Packages (Stored procedure, Functions etc) in oracle using specific key and decrypt using the same key for security purpose??? i am using oracle 12c.... Thanks, 回答1: Yes, you can use the wrap tool for this, see PL/SQL Source Text Wrapping You can wrap the PL/SQL source text, thereby preventing anyone from displaying that text with the static data dictionary views *_SOURCE . In principle decryption is not supported, however you can use tools like Unwrap It!.

问题 My project directory structure is something like this: ProjectName/coursesRegistration/src/coursesRegistration/util When I do "import coursesRegistration.util.FileProcessor; " in Eclipse it works but when I try this on UNIX (using command line compilation) it gives me an error saying "error: package coursesRegistration.util does not exist". Maybe I am missing something very basic, does anyone know what may be the problem? 回答1: If you're trying to do command-line compilation, this is probably
