Hi,

I am using MatCaffe interface for training DNN and was wondering how I could collect training/testing log to for plotting the loss and accuracy v.s. iter/time.

I see in \caffe\tools\extra there are parse_log.py and parse_log.sh for logs plotting purposes but how can they be used for MatCaffe users?

Thanks

Hugo

parse_log (.py or .sh) will not plot anything , it will take the log file and generate two separate files one for training loss & acc. and one for testing loss and acc. both of them can then be imported into matlab easily using some textscan commands. you can even import them into open office calc and draw a chart .

Hi Ahmed,

Thanks for the guide. I commented out in parse_log.sh the column name "' Iters Seconds TrainingLoss LearningRate " for reading convenience, also added ".txt" to the output file $LOG.train.txt and $LOG.test.txt. Otherwise textscan in Matlab won't read .test or .train files.

Thanks

Still I haven't found the command or function for generating loss .log for Matlab interface. For command line interface the command is "2>&1 | tee xxx.log" at the end, but it's unknown for matCaffe as limited instruction could be found.

I have exactly the same problem. No idea how to save the log info when using Matcaffe.
