deepstack_server.lua can't access flop model

[airdine]

Hello,

I am having new issue trying to run deepstack server :

/home/xxxx/torch/install/bin/lua: cannot open <../Data/Models/NoLimit/preflop-aux/final_gpu.info> in mode r at /home/xxxx/torch/pkg/torch/lib/TH/THDiskFile.c:673 stack traceback: [C]: in ?

Do you think I have to train preflop model too, to makes it works ?

Thanks in advance

Hi airdine,

The error said that can't find GPU model of Preflop network (../Data/Models/NoLimit/preflop-aux/final_gpu.info).

Right now, it is provided a CPU model of Preflop network. You can convert it to GPU model using following Lua script.

https://github.com/aikupoker/deeper-stacker/blob/master/Source/Nn/cpu_gpu_model_converter.lua#L41

You just need to change line 41:

From: convert_cpu_to_gpu('../Data/Models/NoLimit/flop/final') To: convert_cpu_to_gpu('../Data/Models/NoLimit/preflop-aux/final')

Cheers,

Hi,

Thanks for the answer and sorry for the poor question. I didn't noticed that the preflop model was cpu...

I just 'correct' (typo error) your answer in case someone come have a look at it

From: convert_cpu_to_gpu('../Data/Models/NoLimit/flop/final') To: convert_cpu_to_gpu('../Data/Models/NoLimit/preflop-aux/final')

Thanks a lot.

Fixed too in my comment. Thanks airdine!
