libraries

问题 I've recently been playing around with python and have now expanded into doing stuff like scraping through websites and other cool stuff and I need to import new libraries for these things like lxml, pandas, urllib2 and such. So I have Python 3.5.1 installed and is also using Wing IDE. I (think) also managed to install pip using this tutorial, but then got lost after the Run python get-pip.py part. So how would I go about installing those libraries to try new projects? Thanks! 回答1: python 3.5

问题 Here I am with a similar question as the last time, and for which I could not find any answer. Note that I consider important: Normally I compile my programs in opencv with the next command: g++ -o def program.cpp `pkg-config --cflags opencv` `pkg-config --libs opencv` This line will create an executable whose name will be def and that I will be able to use. I am working in a project, and as it was getting bigger, I had to define some objects, just to make everything easier and possible to

问题 I'm having a problem when including two libraries (not made by me) into my (pure C) project in Qt Creator (using qmake + GCC on Linux Ubuntu). I know that, to include a lib, one uses the LIBS directive as explained in this SO answer; and I have successfully inserted libraries both in Linux as well as in Windows this way. Even more, in this same problematic project I have two successfully inserted libraries. But now I'm having a problem including this two other libs in this same project. One

问题 I have imported Acrobat Reader using Components | Import Components. The AcroPdf_TLB unit is created in the Imports directory. When I try to use the AcrobatReader component, as follows ... AcroDoc := TAcroPDF.Create(nil); ... I get an 'Unspecified Error' exception (EOleSysError). Any ideas? Thanks, Pieter. 回答1: We use the Adobe Reader plug-in and face this issue often. It particularly surfaces after a user performs a web-update on the Adobe Reader. Try un-installing (via the Control Panel),

问题 I have a problem with having Netbeans compile the way I want to. I can't get Netbeans to compile my program. When I'm in the Ubuntu Terminal I can compile my program with the following command: gcc -L/usr/local/lib -I/usr/local/include/libxml++-2.6 -I/usr/local/lib/libxml++-2.6/include -I/usr/include/libxml2 -I/usr/include/glibmm-2.4 -I/usr/lib/i386-linux-gnu/glibmm-2.4/include -I/usr/include/sigc++-2.0 -I/usr/lib/i386-linux-gnu/sigc++-2.0/include -I/usr/include/glib-2.0 -I/usr/lib/i386-linux

问题 I'm new to Java and IntelliJ and I am just doing a simple "hello world" program. IntelliJ has about 10+ libraries from JDK 1.6 added to my project even though I'm not importing anything in my classes that would seem to need them. I created a new project from scratch. Some of the libraries are alt-rt.jar, charsets.jar, deploy.jar, dnsns.jar, javaws.jar, jce.jar, jsse.jar, localedata.jar, etc. Can anyone explain why those libraries were added? Can I remove those libraries from the Module

问题 How can I specify architecture when I build a library? I need to build a library in armeabi-v7a for an Android project. I found -march option, so this is my command : $ gcc -shared -o liballnet.so -fPIC *.c -march=armv7-a But it doesn't work : error: unknown target CPU 'armv7-a' Any ideas? 来源： https://stackoverflow.com/questions/45805322/gcc-how-to-specify-architecture

问题 I'm trying to explore the difference in how the "gam" function works in the mgcv package versus the gam package. But, I'm not able to run both gam functions in one R session. I thought if I preface with mgcv::gam or gam::gam it would be able to run the right function, but it looks like I have to detach mgcv in order to run the gam function in the gam package. library(ISLR) library(mgcv) library(gam) # I get an error message when it runs this gam.m3 <- gam::gam(wage~s(year,4)+s(age,5)
