Examples with Nd4jNoSuchWorkspaceException org.nd4j.linalg.exception.Nd4jNoSuchWorkspaceException used on opensource projects

Example 1 with Nd4jNoSuchWorkspaceException

use of org.nd4j.linalg.exception.Nd4jNoSuchWorkspaceException in project nd4j by deeplearning4j.

the class BaseNDArray method leverageTo.

/**
 * This method detaches INDArray from current Workspace, and attaches it to Workspace with a given Id.
 * If enforceExistence == true, and no workspace with the specified ID exists, then an {@link Nd4jNoSuchWorkspaceException}
 * is thrown. Otherwise, if enforceExistance == false and no workspace with the specified ID exists, then the current
 * INDArray is returned unmodified (same as {@link #leverage()}
 *
 * @param id ID of the workspace to leverage to
 * @param enforceExistence If true, and the specified workspace does not exist: an {@link Nd4jNoSuchWorkspaceException}
 *                         will be thrown.
 * @return The INDArray, leveraged to the specified workspace
 * @see #leverageTo(String)
