arrays - Vector Subscript out of range in C++ -

-

i facing problem while loading vector array vector rgb array.

after rgbv = pointcloud_rgb[i]; getting error "vector subscript out of range". can guide me please.

regards

suhas

const std::vector<cv::vec3b>& pointcloud_rgb;  (unsigned int i=0; i<points.size(); i++) {     cv::vec3b rgbv(255,255,255);     if (pointcloud_rgb.size() >= i) {         rgbv = pointcloud_rgb[i];     } }

you have off-by-one error.

if pointcloud_rgb.size() == i, i 1 element past end of vector.

to fix this, change condition this:

if (pointcloud_rgb.size() >= i) {

to this:

if (pointcloud_rgb.size() > i) {

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
