Method Detail

initialize
```
public static void initialize()
```
Initializes the native library. Note that this method does not have to be called explicitly, since it will be called automatically when this class is loaded.

setExceptionsEnabled
```
public static void setExceptionsEnabled(boolean enabled)
```
Enables or disables exceptions. By default, the methods of this class only set the cudnnStatus from the native methods. If exceptions are enabled, a CudaException with a detailed error message will be thrown if a method is about to set a result code that is not cudnnStatus.CUDNN_STATUS_SUCCESS

Parameters:

enabled - Whether exceptions are enabled

setLogLevel
```
public static void setLogLevel(LogLevel logLevel)
```
Set the specified log level for the JCudnn library.

Currently supported log levels:
LOG_QUIET: Never print anything
LOG_ERROR: Print error messages
LOG_TRACE: Print a trace of all native function calls

Parameters:

logLevel - The log level to use.

cudnnGetVersion
```
public static long cudnnGetVersion()
```

cudnnGetCudartVersion
```
public static long cudnnGetCudartVersion()
```
Returns CUDA Runtime version statically linked against cudnn

cudnnOpsTrainVersionCheck

public static int cudnnOpsTrainVersionCheck()

 Cross-library version checker..
 This function is implemented differently in each sub-library. Each sublib
 checks whether its own version matches that of its dependencies.

Returns:: CUDNN_STATUS_SUCCESS if the version check passes, CUDNN_STATUS_VERSION_MISMATCH if the versions are inconsistent.

cudnnAdvInferVersionCheck

public static int cudnnAdvInferVersionCheck()

 Cross-library version checker..
 This function is implemented differently in each sub-library. Each sublib
 checks whether its own version matches that of its dependencies.

Returns:: CUDNN_STATUS_SUCCESS if the version check passes, CUDNN_STATUS_VERSION_MISMATCH if the versions are inconsistent.
