is possible slice h5py dataset in 2 subsets without loading them memory? e.g.: dset = h5py.file("/2tbhd/tst.h5py","r") x_train = dset['x'][:n/2] x_test = dset['x'][n/2:-1] no. you need implement own class act view on dataset. an old thread on h5py mailing list indicates such datasetview class theoretically possible implement using hdf5 dataspaces, not worth many use cases. element-wise access slow compared normal numpy array (assuming can fit data memory). edit: if want avoid messing hdf5 data spaces (whatever means), might settle simpler approach. try this gist wrote. use this: dset = h5py.file("/2tbhd/tst.h5py","r") simpleview import simpleview x_view = simpleview(dset['x']) # stores slices, doesn't load memory x_train = x_view[:n/2] x_test = x_view[n/2:-1] # these statements load data memory. print numpy.sum(x_train) print numpy.array(x_test)[0] note slicing support in simple exa...

given have metric (stats.counters.prod.failedbuildmessages) , want extend resolution (stats.counters.prod.failedbuildmessages.1, stats.counters.prod.failedbuildmessages.2, stats.counters.prod.failedbuildmessages.3 etc') don't want lose previous data , still use long can, how can overlay data? seems once add sub counters failedbuildmessages node loses data. is there way it? you should send old metric alongside new one. different metrics if share same hierarchy. i in order have coarser/finer details on metric , works quite well.

i've been having strange problem makefile using order-only prerequisite , parallel mode: when running in sequential mode, first time makefile job, , next times, nothing , returns, expected. when running in parallel mode (-j4 instance), first time job, next times hangs. process blocked doing nothing, doesn't exit. still responsive in sense if terminate using ctrl-c, cleans intermediate files may have created , stops. in parallel mode, if make clean , runs again without problem. likewise, if touch all source files, works (again, in parallel mode). if touch some of source files, runs fine until it's done them, hangs. so created minimal working example, main folder contains folder named 'txt' *.txt file in (could file) , makefile txt_files = $(shell ls txt/*.txt) a_files = $(patsubst txt/%.txt, a/%.txt, $(txt_files)) all: a: $(a_files) dir: @if [ ! -d "a" ]; echo "create directory a" && mkdir -p a; fi a/tmp_%: txt/%...

i have procedure readtokens() takes file , array , tokenizes file , puts things array when access array, full of last element. why? here readtokens() method: void readtokens(char *filename, char** a[]) { file *fp; char *token; int count = 0; fp = fopen(filename, "r"); if (fp == 0) { fprintf(stderr,"file %s not opened reading\n", filename); exit(1); } token = readline(fp); while(!feof(fp)) { a[count] = token; ++count; free(token); token = readline(fp); } fclose(fp); } you should not call free(token) , since still have pointer in a[count] . since you're freeing it, memory can reused, , apparently it's being used when readline() reads next line. each time read line, reuses same memory , overwrites next line. result, elements of a[] contain pointers same line. a[count] = token doesn't make copy of token, assigns pointer. this assumes readline() uses malloc() allocate memory line reads. if doe...
