Constructor Detail

DeepMAR

public DeepMAR(int gpu,
               @Nonnull
               java.lang.String protocolPath,
               @Nonnull
               java.lang.String weightsPath,
               @Nullable
               Logger logger)

Create an instance of DeepMAR. The protocol and weights are directly loaded from local files.

Parameters:

gpu - The GPU to use.

protocolPath - Path of the DeepMAR protocol file.

weightsPath - Path of the binary weights model of DeepMAR.

logger - An external logger.

DeepMAR

public DeepMAR(int gpu,
               @Nullable
               Logger logger)
        throws java.io.IOException

Create an instance of DeepMAR. The protocol and weights are retrieved from the JAR.

Parameters:

gpu - id of GPU to use.

logger - logger for outputting debug info.

Throws:

java.io.IOException
