./dream_go --extract kgs_bal.sgf > kgs_big.bin? about dream-go HOT 3 CLOSED

If you have built the project using cargo then then you can find dream_go in the directory target/release. In the README I shortened the path to just ./dream_go to keep it simple. The full serie of commands, including building the binary if you have not done so already, is:

cargo build --release
./target/release/dream_go --extract kgs_bal.sgf > kgs_big.bin
...

You can of course also copy it to the current directory for future easy access:

cargo build --release && cp target/release/dream_go ./dream_go
./dream_go --extract kgs_bal.sgf > kgs_big.bin
...

thanks this help!
When i build it gets me error below:

`error[E0554]: #![feature] may not be used on the stable release channel

Dream Go requires the nightly branch of rust for various reasons mostly related to performance. You will need to "upgrade" your current stable branch to nightly to compile. It seems like you are using rustup so the following commands should work:

rustup toolchain install nightly
rustup default nightly

If this worked then you should see a version similar to the the one below when running cargo --version:

$ cargo --version
cargo 0.26.0-nightly (1d6dfea44 2018-01-26)

Once you are done compiling Dream Go and you want to switch back to stable you can do so by typing:

rustup default stable

PS: Here are some binaries you can use if you are running Linux (linked against CUDA 9.1 and cuDNN 7). Unfortunately I do not have access to a Mac or Windows machine, so if you are using that then we'll have to see if we can make the compilation work.
