python - latex failure ipython daft matplotlib -


i keen try out daft (http://daft-pgm.org/) , through found out latex functionality not working in matplotlib.

i paste example on daft website (http://daft-pgm.org/examples/nocircles/):

from matplotlib import rc rc("font", family="serif", size=12) rc("text", usetex=true)  import daft  pgm = daft.pgm([3.6, 2.4], origin = [1.15, 0.8], node_ec="none") pgm.add_node(daft.node("cloudy", r"cloudy", 3, 3)) pgm.add_node(daft.node("rain", r"rain", 2, 2)) pgm.add_node(daft.node("sprinkler", r"sprinkler", 4, 2)) pgm.add_node(daft.node("wet", r"grass wet", 3, 1)) pgm.add_edge("cloudy", "rain") pgm.add_edge("cloudy", "sprinkler") pgm.add_edge("rain", "wet") pgm.add_edge("sprinkler", "wet") pgm.render() pgm.figure.savefig("nocircles.pdf") pgm.figure.savefig("nocircles.png", dpi=150)

this ipython returns me

runtimeerror: latex not able process following string:   'lp' here full report generated latex:

there no report supplied ipython or latex. see screenshot:

enter image description here

the standard script on matplotlib website gives me same error. there way check if dependencies met? latex installed on system not sure if ipython can access it.

in case latex library needed installed (sorry didn't pay attention one)

it automatically opened miktex installer, install suggested library , should done.

there no need 'lp' accessible command line.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
