Function: set_model_dir

aclError aclopSetModelDir(const char *modelDir)

ret = acl.op.set_model_dir(model_dir)

Sets the directory to store the model file, which is an *.om file built from a single operator.

model_dir: str, directory where the specified model file is stored.

A multi-level directory is supported. However, the system reads the model up to three levels down from the last level.

For the example, if modelDir is set to dir0/dir1 and dir1 contains dir2/dir3/dir4, the system looks up for the model file in dir1, dir1/dir2 and dir1/dir2/dir3 only.

ret: int, error code.

• 0 indicates success.
• Other values indicate failure.

Before loading the model file, check whether the memory space is sufficient based on the file size. If the memory space is insufficient, the application will be abnormal.
