python - QPixmap Line Being Skipped -

-

i have following piece of code:

def run(self):         filename = qtgui.qfiledialog.getsavefilename(self, "save file", "", ".inp")         if filename == "":             pass         elif filename != "":             nfile = open(filename, 'w')             self.pixmap1 = qtgui.qpixmap('yellow.jpg')             self.canvas1.setpixmap(self.pixmap1)             self.cursor.moveposition(self.cursor.start, self.cursor.moveanchor)             self.cursor.moveposition(self.cursor.end, self.cursor.keepanchor)             text = self.cursor.selection()             text1 = text.toplaintext()             nfile.write(text1)             nfile.close()             fileinfo = qtcore.qfileinfo(filename)             name = fileinfo.basename()              import os             os.system("rungms {}.inp 13-64 {} {} {}.out".format(name, self.cores_val, self.clusters_val, name))              itertools import islice             import sys              open("{}.out".format(name)) searchfile:                 line in searchfile:                     if 'terminated normally' in line:                         self.pixmap1 = qtgui.qpixmap('green.jpg')                         self.canvas1.setpixmap(self.pixmap1)                     elif 'job aborted' in line:                         self.pixmap1 = qtgui.qpixmap('red.jpg')                         self.canvas1.setpixmap(self.pixmap1)                     else:                         pass         else:             pass

my problem 2 lines involving qpixmap('yellow.jpg') not being read after saving file. however, if move these 2 lines in between first , second lines of code (i.e. before filename = qtgui...), work.

can explain me why case?

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 .
