I run ray throwing an error! help me

[leesng]

(/root/anaconda3/envs/cntk-py35) root@leenux:/Ray# ./ray
Init CNTK
terminate called after throwing an instance of 'Microsoft::MSR::CNTK::ExceptionWithCallStackstd::runtime_error'
what(): no closing " found in parameters

Do you use linux?
Maybe a parameter of CreateNetwork() is something wrong.
Please edit src/UctSearch.cpp like below, and let me know.

cerr << "CreateNetwork('" << networkConfiguration << "')" << endl;
nn_model->CreateNetwork(networkConfiguration);

[leesng]

yes, i use ubuntu16.4,

cntk ver : CNTK for Linux v.2.0 Beta 12 GPU with 1bit-SGD
install-cmd : ./install-cntk.sh --py-version 35

I have added printing-code and the log is here:

(/root/anaconda3/envs/cntk-py35) root@leenux:/Ray# ./ray
Init CNTK
CreateNetwork('modelPath="./uct_params/model.bin"')
terminate called after throwing an instance of 'Microsoft::MSR::CNTK::ExceptionWithCallStackstd::runtime_error'

[zakki]

Thank you, it seems no problem.

@bihonglu Do you know something about this?

[bihonglu]

Don't know anything about this. But the way, when I did Ubuntu 14.04, I did not use 1bit-SGD.
I forgot what it is, but it was not suitable for my situation.

[leesng]

i use cntk without 1bit-sgd, the log is this:

(/root/anaconda3/envs/cntk-py35) root@leenux:/Ray# ./ray
Init CNTK
CreateNetwork('modelPath="./uct_params/model.bin"')
terminate called after throwing an instance of 'Microsoft::MSR::CNTK::ExceptionWithCallStackstd::runtime_error'
what(): configparameters: required parameter missing: unknown:modelPath
已放弃 (核心已转储)
(/root/anaconda3/envs/cntk-py35) root@leenux:/Ray#

if i use cmd :/root/Ray/ray, then log:
(/root/anaconda3/envs/cntk-py35) root@leenux:/Ray# /root/Ray/ray
Init CNTK
CreateNetwork('modelPath="/root/Ray/uct_params/model.bin"')
terminate called after throwing an instance of 'Microsoft::MSR::CNTK::ExceptionWithCallStackstd::runtime_error'
what(): unmatched bracket found in parameters

[zakki]

Is it CNTK configuration problem?

"I can build my application using EvalDll.lib/dll, but got the exception like below when running"
https://github.com/Microsoft/CNTK/wiki/Troubleshoot-CNTK

[leesng]

yeah,i use g++-4.8, it works.thx.

But,the first time,it is ok; then it simply exits after that：

(/root/anaconda3/envs/cntk-py35) root@leenux:/Ray# ./ray
Init CNTK
CreateNetwork('modelPath="./uct_params/model.bin"')
ok
(/root/anaconda3/envs/cntk-py35) root@leenux:/Ray#

[zakki]

Some time ray exits, other time ray works on linux.
Maybe there are some bugs something like memory corruption or race condition.

[leesng]

why the 1st move is : move 1 to # move 7 ?

(/root/anaconda3/envs/cntk-py35) root@leenux:~/Ray# ./ray
Init CNTK
ok

fgets in GTP_main() sometimes returns NULL.
A patch below fix, but I'm not sure it is legal or not.

-  while (fgets(input, sizeof(input), stdin) != NULL) {
+  //  while (fgets(input, sizeof(input), stdin) != NULL) {
+  while (true) {
+    if (fgets(input, sizeof(input), stdin) == NULL)
+      continue;

[leesng]

yes, i have fixed the bug, and there are my pacths:

0002-Fix-the-fgest-return-null-bug-some-times.patch.txt
0001-Change-Makefle-to-compile-RayGo-using-CNTK-libs-in-u.patch.txt

[leesng]

i think it is need clean the stdin buffer，before fgets

[zakki]

Fixed 0002

[antifermion]

The error is due to ABI changes. The binaries of CNTK provided by Microsoft appear to be compiled with gcc-4.8. With 5.1 I think they changed the ABI. You can still use the old ABI with compiler argument -D _GLIBCXX_USE_CXX11_ABI=0.
