I can't use a split protocol buf file

[isu51004]

Hello, Thank you for using the code you posted.

As a matter of fact, I have more than 2GB of protocol buf files.

So, I used split_proto_netlist_main.py to split it, I successed.

As stated in README, I passed as below as by inputting the grouping_main.py
--netlist_file=/path/to/netlist_file_1.pb.txt,/path/to/netlist_file_2.pb.txt

However, during execution, an error occurs in which the path is not found as shown below.

tensorflow.python.framework.errors_impl.NotFoundError: /home/soooh1_lim/circuit-training/SOO.part1.pb.txt,/home/soooh1_lim/circuit-training/SOO.part2.pb.txt; No such file or directory
In call to configurable 'create_placement_cost' (<function create_placement_cost at 0x7fef0c42e670>)
