16: [0x1095] ??() ??:0So this seems to be a parsing error, pertaining to the data.csv file. I reproduced it from the "tutorial" video. Here it is:
mini-me@virtucon ~/h/s/mud-asmoses (master)> cat data.csv
o, f1, f2, f3
1, 1, 1, 1
0, 0, 0, 0
1, 1, 0, 1
0, 0, 1, 0So, basically, the "tutorial" example seems to not be adapted to the evolution over time of moses / asmoses. There seemingly is a confusion between integers and booleans.

Launched a gdb debugging session. The problem can be identified in table_io.cc:tokenizeRowIOT:786. On line 792, there is a call to get_row_tokenizer. The toker variable thus obtained, containing the tokenisation of line "1, 1, 1, 1"of the above data.csvfile, splits it up like ["1", ",", " ", "1", ",", " ", "1", ",", " ", "1"]. The first item is identified as the output. Remains 9 items that gets converted to "", "", "1", "", "", "1", "", "", "1" instead of "1", "1", "1". The latter could be converted to booleans, but the former can't. And we get the former. And the code hence crashes.

To avoid the problem highlighted on this issue, one may use tabs instead of ", ". For instance:
o[tab]f1[tab]f2[tab]f3
1[tab]1[tab]1[tab]1
0[tab]0[tab]0[tab]0
1[tab]1[tab]0[tab]1
0[tab]0[tab]1[tab]0This satisfies the boost::tokenizer. And allows to then follow the tutorial mentioned in the opening comment.
However, the tokenizer seems broken as it should accept ", " as a separator and it does not do so. So CSV support seems to me to be broken. Which is why I am not closing this issue.

This sounds like a correct diagnosis of the problem. I don't know why the tokenizer is not respecting commas. @ngeiswei can you look at this?

Removing the spaces after the commas also fixes the problem.

This indeed fixes the issue.
