Where is log file in caffe-windows

[cheer37]

Training with caffe-windows, logs like below out periodically in console.
"Could not create logging file: File exists."
I guess this means log file exists already, so can't create it.
But where is the log file in default? and how can i redirect the path to save the log file?
Thanks.

Thank you.
I found that log file, but that file contains only net information, not training course reflecting the loss and accuracy.
What's wrong?

Log file in the %temp% folder should contain training progress as well. What happens when you add following lines of code at the beginning of cafe.cpp in caffe project:

  boost::filesystem::create_directory("log");
  ::google::SetLogDestination(0, "log/");
  ::google::SetLogFilenameExtension("Caffe.log.");

This should create a log directory in your working directory and force log file starting with "Caffe.log" to be written there.

Thank you sasagalic-MSFT.
The instructions you offered work correctly and i found the reason why log.info file does not contain the training progress.
caffe training was failed due to out of memory at first, the log file was made from it.
when caffe trains successfully, caffe couldn't create the log file because there is already a log file made from broken training, so it had logged out "Could not create logging file: File exists."
I removed the broken log file and run the caffe again, so new log file happened and reflects all progress correctly now.
By the way, why this log.info file does not suffix the date and time information?
As i know, the log file should be suffixed date and time information.
That's why the log files from every caffe running conflicts.

@cheer37 if this issue is resolved please close it.

I am still not sure why date and time information is not suffixed to log file.
The log file name is like this - caffe.exe.WIN-AE2MD73M7I6.Administrator.log.INFO
But as i know, it should be like this - caffe.exe.WIN-AE2MD73M7I6.Administrator.log.INFO.20160329-084042.9160.
What's the reason?

@cheer37 I have never seen the logs without data-time.pid suffix. That seems like issue with your system or glog, not the Caffe.

[cheer37]

ok, i will investigate more. Thanks.
