windows - New to Python (3.4.3), trying to pip install basic libraries and receiving this message -

-

command "c:\python34\python.exe -c "import setuptools, tokenize;__file__='c:\\users\\jamey\\appdata\\local\\temp\\pip-build-4xxi4hts\\numpy\\setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record c:\users\jamey\appdata\local\temp\pip-l8qukpar-record\install-record.txt --single-version-externally-managed --compile" failedwith error code 1 in c:\users\jamey\appdata\local\temp\pip-build-4xxi4hts\numpy

it has lot of errors, need add basic libaries before installing more advance ones? tells me need microsoft visual c++ 10.0

for numpy , other such libraries, these difficult build on windows because need compiled during installation. setting proper build environment difficult on windows.

you have few choices:

  1. download build of python includes these libraries. popular package of python includes numpy (and other scientific libraries) anaconda. scipy download page lists more options you.

  2. download pre-compiled binaries windows. these available standard windows installers. example here link downloads numpy 1.9 (you can download windows installer there).

  3. a list of pre-compiled python modules windows available here. suggest bookmark page , when have trouble installing on windows, chances listed there.

if downloading packages, make sure download right version of python. if there 2 versions (a 64 bit , 32 bit) available, this refers version of python not windows have installed.

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...

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 .
