Problem compiling code from Smilearn tutorial

[Mauro]

I compiled and used with no problem the code from the Smile tutorial in the wiki. However, when doing this for the first Smilearn tutorial i get the following from make:

g++ -O3 -DNDEBUG -ffast-math -c smile.C -I../include_gcc_411
smile.C: In function ‘void PrintDataset(const DSL_dataset&)’:

Searching with grep, for example, for NumVariables in the header files i actually didn't find it, but the similar GetNumberOfVariables(). This replacement actually spared me the errors for Numvariables, but the replacemente for the other errors dont appear to be so obvious.I'm thinking maybe there's been changes in the code that haven't been updated in the tutorial??

Thanks in advance for any help, and as this is my first post, i also would like to thank everyone behind Genie/Smile for providing the community with such an awesome tool!

ps: My Makefile:

CFLAGS = -O3 -DNDEBUG -ffast-math
CC = g++
SMILE = ../include_gcc_411
LFLAGS = -L$(SMILE) -lsmile -lsmilearn

default: smile

smile: smile.o
$(CC) $(CFLAGS) smile.o -o smile $(LFLAGS)

smile.o: smile.C
$(CC) $(CFLAGS) -c smile.C -I$(SMILE)

clean:
rm -rf *.o smile

There have been some changes in the public API of SMILE, but the tutorials have not been updated yet. NumVariables has been replaced with GetNumberOfVariables, NumRecords has been replaced with GetNumberOfRecords, and At has been replaced with GetInt/GetFloat. Please see dataset.h for more information.

I did look at it briefly, and now will look with more depth. Still, if you could tell me about how to replace DSL_variableInfo and DSL_dataElement i think it would be a great help.

Thanks for the quick response!

DSL_variableInfo has been replaced by DSL_datasetVarInfo. You can use GetFloat/GetFloat to retrieve data set values instead of DSL_dataElement which has been removed.

[Mauro]

I forgot to ask if there is some code available that works with the last version of the code; nothing fancy as in the tutorial perhaps, but something that will easily compile and run to perform some inference??

[mark]

The tutorials are supposed to be our examples, so I guess we should really update them. I'd be glad to help you develop a simple example though.

Hi,

I'm having the same problems Mauro had.
It would be great if you could update the wiki and the tutorials.

In the meantime... how can I fix ‘struct DSL_datasetVarInfo’ has no member named ‘missingValue’?

Thanks for providing such a great tool!

DSL_datasetVarInfo::missingValue was replaced by missingInt and missingFloat.

Hi,

Could you also help out with the methods for adding a vector to a dataset.

AddIntVar and AddFloatVar don't seem to accept vectors anymore.

Thanks.

[shooltz[BayesFusion]]

AddIntVar and AddFloatVar don't seem to accept vectors anymore.

You need to iterate over the vector and call SetInt/SetFloat with appropriate parameters. If the dataset row count is different from vector's size, use AddEmptyRecord or RemoveRecord.
