Discussion:
There seems to be regression in the dynamo export of the MONAI VNet model as regards . Export script: The versions I'm using is torch 2.5.0.dev20240625+cu121 Previous torch versions such as were able to export this model successfully. Perhaps dynamo was generating FX graph without the expm1 node previously? cc: PyTorch version: 2.5.0.dev20240625+cu121 Is debug build: False CUDA used to build PyTorch: 12.1 ROCM used to build PyTorch: N/A OS: Ubuntu 22.04.4 LTS (x8664) GCC version: (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0 Clang version: Could not collect CMake version: version 3.29.0 Libc version: glibc-2.35 Python version: 3.10.12 (main, Nov 20 2023, 15:14:05) [GCC 11.4.0] (64-bit runtime) Python platform: Linux-6.5.0-35-generic-x8664-with-glibc2.35 Is CUDA available: True CUDA runtime version: 12.4.131 CUDAMODULELOADING set to: LAZY GPU models and configuration: GPU 0: NVIDIA RTX A5000 Nvidia driver version: 535.171.04 cuDNN version: Probably one of the following: /usr/lib/x8664-linux- /usr/lib/x8664-linux- /usr/lib/x8664-linux- /usr/lib/x8664-linux- /usr/lib/x8664-linux- /usr/lib/x8664-linux- /usr/lib/x8664-linux- /usr/lib/x8664-linux- HIP runtime version: N/A MIOpen runtime version: N/A Is XNNPACK available: True CPU: Architecture: x8664 CPU op-mode(s): 32-bit, 64-bit Address sizes: 46 bits physical, 48 bits virtual Byte Order: Little Endian CPU(s): 20 On-line CPU(s) list: 0-19 Vendor ID: GenuineIntel Model name: Intel(R) Core(TM) i9-9820X CPU @ 3.

I am not very sure, but this looks like the kind of ops that should get decomp'ed. do you know? could you help take a look as part of the op support work you are doing? Thanks!
Yes, it looks like there is a graph-changed in dynamo, which dynamo now decomposes elu for some reasons. Using can preserve elu and then successfully export though.

Yes can run but we would need to be resolved first since the weights are still not exported properly.
I can take a look at this.
should fix this.

Here, I can't export trivial net with sort() using dynamoexport(). Legacy () works fine, dynamoexport errors out : Unsupported FX nodes: {'callfunction': ['']}. Pytorch nightly 06/03 cc
a missing op, could you take this?
Not sure if related:
Hmmm. Ideally, ONNX should add a sort op. It doesn't have one. I wonder what the legacy exporter converts it to.
should fix this issue.

Are there any plans to implement something like tensorflow's and ? exists but it doesn't have the backward step implemented.
One workaround for the moment would be to write as , which should support backprop since . Adding support for should be trivial, the gradient for it can be found in
I'll add backward support for , which should be equivalent to . I'll try to do it later today.
How difficult would it be to add in batched versions (where only the final two dimensions are square) of GESV and inverse? Are there any plans for this?
If we have batched version of , then adapting the autograd part is very simple. There is an open issue already that discuss implementing batched gesv
Actually, there is an open PR for that, so it might be coming soon
I'll rebase the batched version of gesv. It'll come in soon
May I ask why gesv only support . As I saw from , it support that A is a MxN matrix, and B is a NxK matrix, then solve a matrix X (NxK). If I want to use a non-square matrix A in gesv, would you mind to let me know how to implement in PyTorch?
this doesn't exactly answer your question but you can add zero-rows to the A matrix until it becomes square.
thanks a lot, I find the solution, can solve the problem.
Any plan to add gradient calculation for gels?
I am also wondering if will have differentiation support. My current workaround is to use instead
I actually implemented overdetermined case following tensorflow implementation. For backward pass I only did basic grad test. On Monday, March 18, 2019, Johnson Zhong <:
Thanks, seems to work fine!
