[TVM Discuss] [Questions] [External Codegen] Constant tensors in c-codegen

2020-04-03 Thread Trevor Morris via TVM Discuss
@masahi I see, thanks for sharing. I also thought about an approach like this. It seems like a lot of additional overhead to create and maintain a whole new IR for serialization. Since it seems to be the case that many external codegens (not just TRT) will need to do something like this, I won

Hi @masahi, that is correct. I am using [TVM's native json serialization API](https://github.com/neo-ai/tvm/blob/dev/include/tvm/node/serialization.h#L39-L48) to serialize the relay subgraphs during codegen and deserialize it in the runtime for my TRT integration. I am curiously what binary f

[TVM Discuss] [Questions] External codegen with CUDA target

2020-03-31 Thread Trevor Morris via TVM Discuss
Hi @jonso, when I do relay.build with target="cuda", the data inputs supplied to my runtime module are already placed on the GPU by the graph runtime.The DLTensor->data will be a device pointer to the data in GPU memory and you can pass this directly to CUDA libraries. If you need to get the
