  Sorry to be annoying but I thought it was nice to give you some news as well. I was confused as to why there isnt yolo in pytorch, here it is why https://github.com/pytorch/vision/issues/6341

• [Discussion] Stochastic Depth with BatchNorm ?
  2 projects | reddit.com/r/MachineLearning | 26 Dec 2022

  My question is more related to the variance of the batchs. If one batch contains samples that skip a connection and samples that do not ('row' mode in the Torchvision implementation), even if the values are ajusted to preserve the expected value, the variance will be much higher because we have in practice two distributions (for x_n and x_n + f(x_n)/p), which will mess up with the update of the batch normalization. Also, at inference time, all forward passes will be done as x_{n+1} = x_n + f(x_n), which has a different variance. The torchvision implementation also offers a 'batch' mode that kinda reduce this issue (because the global variance computed this way will be the mean of both distribution variances, instead of the variance of the joint distribution) but it does not seem to be the default mode (it does not even exist in the timm implementation).

• Solution for "RuntimeError: Couldn't load custom C++ ops"
  2 projects | reddit.com/r/StableDiffusion | 7 Sep 2022

  RuntimeError: Couldn't load custom C++ ops. This can happen if your PyTorch and torchvision versions are incompatible, or if you had errors while compiling torchvision from source. For further information on the compatible versions, check https://github.com/pytorch/vision#installation for the compatibility matrix. Please check your PyTorch version with torch.version and your torchvision version with torchvision.version and verify if they are compatible, and if not please reinstall torchvision so that it matches your PyTorch install.

• Hey, I'm trying to find some materials about object detection in Pytorch but I'm having a hard time finding it.

  And there are explanations: it's the research articles as well as the blog articles talking about them. And 99% of the code you'll find is open sourced: - The official torchvision has various models described here with their reference papers and the code of these models is found on the gitub page - You can find almost-official YOLO implementation on this github page.

• PyTorch 1.10

  haha, yes, but that requires you to modify existing code to do so (which isn't always possible!).

  There might also be other things you want to do (like add profiling after each op) that would be tedious to do manually, but can easily automated with FX (https://pytorch.org/tutorials/intermediate/fx_profiling_tuto...).

  Another example is the recent support from torchvision for extracting intermediate feature activations (https://github.com/pytorch/vision/releases/tag/v0.11.0). Like, sure, it was probably possible to refactor all of their code to enable users to specify extracting an intermediate feature, but it's much cleaner to do with FX.

  Not quite - it's more of a platform for users to write their own transformations on their PyTorch code.

  This can include things like doing operator fusion/lowering to a backend compiler, but can also include things like inserting profiling instrumentation (https://pytorch.org/tutorials/intermediate/fx_profiling_tuto...) or extracting intermediate features (https://github.com/pytorch/vision/releases/tag/v0.11.0).

  Basically, if you want a graph representation of a PyTorch module that's really easy to modify, use torch.fx :)
