SK-TDA4VM: Unsupported slice - axis parameters

Part Number: SK-TDA4VM

Tool/software:

Hi TI team,

I'm working on converting the custom onnx model using edgeai-tools (09_01_07_00). During the conversion process,  I've encountered some issues:

 Unsupported slice - axis parameters, in Slice -- /Slice_3

 Unsupported slice - axis parameters, in Slice -- /Slice_2

 Unsupported slice - axis parameters, in Slice -- /Slice_1

 Unsupported slice - axis parameters, in Slice -- /Slice

Could you confirm that this issue is related to the limitation regarding Slice layer (according to documentation: Only channel wise slice is supported)?

I've added Slicing layers to the deny_list, which allowed the model to be converted. However, this results in 4 subgraphs being created.

Apparently, the issue appears due to unsupported batch wise slicing – is there any workaround to avoid this?

The model is very complex, and we want whole model to be execute on DSP + MMA. If you have any suggestions on how to achieve this, it would be very helpful. Updating the ONNX model is the last option for our customer, so any solution that avoids modifying the model would be preferred.

Thank you for the support!

Kind regards,
Nevena

  • Hi,

    On 9.1 sdk we dont support slice along the batch dimension.

    From 9.2 sdk onwards we are supporting internally by squashing last to dims (batch and channel) as part of import tool.

    Can you please migrate to lasted sdk and check the supportability please ?
