Unable to train the system

[rohit-takhar]

Hi,
I am trying to follow the instructions and run the training but it is throwing some error:
INFO: Running command line: bazel-bin/n2p/training/train_json F0216 01:49:19.235635 32541 readerutil.h:89] Check failed: exists(filename) File 'testdata' does not exist! *** Check failure stack trace: ** @ 0x7fb5ff9245cd google::LogMessage::Fail() @ 0x7fb5ff926433 google::LogMessage::SendToLog() @ 0x7fb5ff92415b google::LogMessage::Flush() @ 0x7fb5ff926e1e google::LogMessageFatal::~LogMessageFatal() @ 0x40ee5a FileInputRecordReader<>::FileInputRecordReader() @ 0x42b44b FileRecordInput<>::CreateReader() @ 0x42b215 ShuffledCacheInput<>::CreateReader() @ 0x4152b4 ParallelForeachInput<>() @ 0x412097 InitTrain<>() @ 0x410a92 LearningMain<>() @ 0x40d97a main @ 0x7fb5fecce830 __libc_start_main @ 0x40d4a9 _start @ (nil) (unknown)
Can somebody please help me in sorting this out? I tried putting json training file with the name testdata also but nothing seems to work.

Thanks,
Rohit

Hi @rohit-takhar !

Sorry for not replying to you that long. I accidentally introduced an incorrect error message. You should provide a dataset using the -input option.

Fixed in #19

Hi @onponomarev
Thank you. I was able to train the model. But I am facing couple of issues while running the server. First, there is no nice2serverproto target and while running nice2server, I don't know the exact path where model is stored(I need to pass it using -model option). I tried looking around but didn't find any files being updated in the directory.
Thanks for your help in advance.

Hi @rohit-takhar
When you train a model, n2p saves it to a couple of files named model_{strings,features}. If you don't have such files, that means that something went wrong. Run train with --logtostderr option to know, what. Also, you can try --checkpoints option that will save an intermediate model each training iteration.

Hi @onponomarev,
Thanks for your help! Everything was running fine but it was not dumping the models without any error. I just chamged the model file name with absoulte path to my home directory and it dumped the model.
