i have git branch need copy 1 repository branch within repository. from: repo_a branch: develop top: repo_b branch: whatever i cannot mirror repo_a repo_b repo_b has restrictions on commits, must go branch, approved others, , merged master branch. what best way go doing this? should clone repo_a, checkout branch 'develop', create branch on repo_b , copy contents of 'develop' new branch , push changes? or there better strategy? you add other remote can call repo_a on local git, pull repo_a new branch can call branch_repo_a, make new branch branch want merge let's in repo_b have branch dev checkout new branch repo_b/dev can call dev_a_b (do new branch repo_b in case somenthing goes wrong merge) then merge in dev_a_b git merge branch_repo_a and there have code merge, did not ask merge suggestion, :)

when use atob, encodeuricomponent, btoa, decodeuricomponent. suppose used i.e., atob(encodeuricomponent(...))? if not, when atob&btoa used , when encodeuricomponent&decodeuricomponent used. btoa() encodes string of binary data in base-64 format. common use of creating data: uri contents of file (e.g. turning jpeg or gif file data: uri incorporate directly page instead of referencing remote file). atob() performs opposite: given base-64 string, returns binary data. encodeuricomponent() used perform url-encoding of strings used in uri. converts characters have special meaning in uris % followed hex encoding, e.g. space becomes %20 . used when creating url parameters used in redirects or ajax requests, or data sent in xmlhttprequest.send() . decodeuricomponent() performs reverse of encodeuricomponent() , if have "foo%20bar" return "foo bar" . it's pretty rare need use both url-encoding , base-64 same string.

plotly supports catmull-rom splines interpolation of lines between markers on scatter plot. i have graphs data fundamentally normal distribution. cubic or hermite interpolation works type of data in other graphing frameworks - unfortunately catmull-rom splines (or @ least plotly's implementation of them) doesn't. i've experimented values of "smoothing" between 0.0 , 1.0 (it seems, though not documented, values on 1.0 make no further difference). unfortunately, bad. i've seen suggestion elsewhere might make sense own interpolation using scipy's interpolate.interp2d, , graph line separately. however, fails use case, since want color of line paired color of markers, , both appear on legend single item, shown above. has had experience making plotly splines nicer on quasi-normal distribution using smoothing=1.0?

i trying understand spark hivecontext . when write query using hivecontext sqlcontext=new hivecontext(sc) sqlcontext.sql("select * tablea inner join tableb on ( a=b) ") is using spark engine or hive engine?? believe above query executed spark engine. if thats case why need dataframes? we can blindly copy hive queries in sqlcontext.sql("") , run without using dataframes. by dataframes, mean tablea.join(tableb, === b) can perform aggregation using sql commands. 1 please clarify concept? if there advantage of using dataframe joins rather sqlcontext.sql() join? join example. :) the spark hivecontext uses spark execution engine underneath see spark code . parser support in spark pluggable, hivecontext uses spark's hivequery parser. functionally can sql , dataframes not needed. dataframes provided convenient way achieve same results. user doesn't need write sql statement.

how weights of filters (like 32 ,64, etc.) of conv2d layer in keras after each epoch? mention that, because initial weights random after optimization change. i checked this answer did not understand. please me find solution of getting weights of filter , after every epoch. and 1 more question in keras documentation conv2d layer input shape (samples, channels, rows, cols). samples mean? total number of inputs have (like in mnist data set 60.000 training images) or batch size (like 128 or other)? samples = batch size = number of images in batch keras use none dimension, meaning can vary , don't have set it. although dimension exists, when create layer, pass input_shape without it: conv2d(64,(3,3), input_shape=(channels,rows,cols)) #the standard (rows,cols,channels), depending on data_format to have actions done after each epoch (or batch), can use lambdacallback , passing on_epoch_end function: #the function call def get_weights(epoch,logs): wsan...
