| 37 | --- Unsupported operators --- |
| 38 | |
| 39 | The following AndroidNN operations are currently not supported. |
| 40 | |
| 41 | DEPTH_TO_SPACE |
| 42 | DEQUANTIZE |
| 43 | EMBEDDING_LOOKUP |
| 44 | HASHTABLE_LOOKUP |
| 45 | LSH_PROJECTION |
| 46 | LSTM |
| 47 | RNN |
| 48 | SPACE_TO_DEPTH |
| 49 | SVDF |
| 50 | |
| 51 | Where operations are not supported by the ArmNN Android NN Driver, the driver indicates this to the framework appropriately and the framework implements those operations using a CPU implementation. |
