[gem5-users] Error with syscall 318 for gem5, when executing with a multi agent reinforcement learning algorithm

I'm trying to execute a python algorithm (*https://github.com/shariqiqbal2810/maddpg-pytorch *) on gem5 in se mode in X86. But, at first I got an *error syscall 318 out of range*. So, I tried to import the get random function into the

I'm trying to port maddpg on top of gem5 Here's my process: First I've downloaded the maddpg from open ai: https://github.com/openai/maddpg (I've also installed all the dependencies for maddpg on the multi-particle environment) In the next step, I used the following command to train the maddpg o

Hello mohit, But my problem is we shouldn't modify the program binary, instead when the simulator process the binary, when it triggers fopen syscall, it should should open a different file instead of already specified one. Here, as this is in the hardware level, I guess we can't see the filename

Hello, I have a C code, which creates a file *file.txt* and prints the hello world content in the file. #include int main () { FILE *fp; char str[] = "Hello world"; fp = fopen( "file.txt" , "w" ); fwrite(str , 1 , sizeof(str) , fp ); fclose(fp);
