How can I run Tensorflow on one single core? -

-

i'm using tensorflow on cluster , want tell tensorflow run on 1 single core (even though there more available).

does know if possible?

to run tensorflow on 1 single cpu thread, use:

session_conf = tf.configproto(       intra_op_parallelism_threads=1,       inter_op_parallelism_threads=1) sess = tf.session(config=session_conf)

device_count limits number of cpus being used, not number of cores or threads.

tensorflow/tensorflow/core/protobuf/config.proto says:

message configproto {   // map device type name (e.g., "cpu" or "gpu" ) maximum   // number of devices of type use.  if particular device   // type not found in map, system picks appropriate   // number.   map<string, int32> device_count = 1;

on linux can run sudo dmidecode -t 4 | egrep -i "designation|intel|core|thread" see how many cpus/cores/threads have, e.g. following has 2 cpus, each of them has 8 cores, each of them has 2 threads, gives total of 2*8*2=32 threads:

fra@s:~$ sudo dmidecode -t 4 | egrep -i "designation|intel|core|thread"     socket designation: cpu1     manufacturer: intel             htt (multi-threading)     version: intel(r) xeon(r) cpu e5-2667 v4 @ 3.20ghz     core count: 8     core enabled: 8     thread count: 16             multi-core             hardware thread     socket designation: cpu2     manufacturer: intel             htt (multi-threading)     version: intel(r) xeon(r) cpu e5-2667 v4 @ 3.20ghz     core count: 8     core enabled: 8     thread count: 16             multi-core             hardware thread

tested tensorflow 0.12.1 , 1.0.0 ubuntu 14.04.5 lts x64 , ubuntu 16.04 lts x64.

java - Static nested class instance -

this question has answer here: java inner class , static nested class 23 answers i came across in java, know static nested class why create instance of 'static'. isn't whole idea of 'static' use without instance? understand concept of inner classes, why (and frankly how possible to) create 'instance' of 'static' member @ ? why this: 1- outerclass.staticnestedclass nestedobject = new outerclass.staticnestedclass(); 2- nestedobject.anestedclassmethod(); and not this: 1- outerclass outerinstance=new outerclass(); 2- outerinstance.staticnestedclass.anestedclassmethod(); use on inner classes, keyword static indicates can access inner class without instance of outer class. for example: public class outer { public static class inner { /* code here. */ } } with construction, can create instance of inn

JavaScript - Replace variable from string in all occurrences -

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
