cannot train probabilistic grammar with error

[WonHoYoo]

Currently I am running the chimera ChiGen tutorial on my Window WSL2 ubuntu shell.

After cloning the repository, the error message popped up after commanding "Train probabilistic grammar" as below

_asus@DESKTOP-DROQ9QQ:~/verilog_test/chimera$ ./scripts/run_parser_count_productions.sh ./database verible-verilog-syntax grammar.json
Usage: ./scripts/run_parser_count_productions.sh <verible_parser_executable> <output_file>

I am using the ChiGen in main branch, and could you be able to check what happening on here?

Hey, I faced this issue as well, and using absolute paths worked for me. Additionally, building verible-verilog-syntax from source also helps.

./scripts/run_parser_count_productions.sh <absolute-path-to-database-folder> <absolute-path-to-verible-verilog-syntax> grammar.json

Hi @WonHoYoo,

Firstly, thank you @mohitk05 for the comment, as you clarified ChiGen's executable needs the path to Verible's parser executable. Therefore you could run it like this:

_asus@DESKTOP-DROQ9QQ:~/verilog_test/chimera$ ./scripts/run_parser_count_productions.sh ./database ./verible-verilog-syntax grammar.json
