torch.clone — PyTorch 1.10.0 documentation torch.clone torch.clone(input, *, memory_format=torch.preserve_format) → Tensor Returns a copy of input. Note This function is differentiable, so gradients will flow back from the result of this operation to input. To create a tensor without an autograd relationship to input see detach (). Parameters

09.08.2019 · I use pytorch C++ interface. I need to do deep copy for modules. I think I am going to go with this route: 1) dump one module onto the disk using torch save, 2) load the dumped file into a new module class.

Default copy constructor just copy the sub-module pionters. · cloneable.clone() just cloned members with recursive=false.

13.04.2020 · Hi all, I’m working on a implementation of MAML (paper link). There’s a few implementations out there but from what can see they all rely on the functional form of a model. I have a requirement to make this as general as possible so it can be used with a variety of underlying models. To that end I would like to be able to copy a nn.Module instance in the …

12.03.2019 · clonecan be used e.g. on activations, which should be passed to multiple modules, where each module might manipulate the activation in-place. Here is a small example: # Setup module1 = nn.Sequential( nn.ReLU(inplace=True), nn.Linear(10, 1)) module2 = nn.Sequential( nn.Linear(10, 2)) torch.manual_seed(2809) act = torch.randn(1, 10)

11.09.2020 · How to deep clone a network (module) by C++ API? I’ve read topic Are there any recommended methods to clone a model?. Seemed that there are off-the-shelf methods for Python applications. Then what’s the corresponding method for C++ application? Any extra work (e.g. interface implementation) required for customized module? Thank you very much.

Module so that the same parameters can be accessed from multiple processes ... and I want each subprocess to get an independent copy of the ...

module – child module to be added to the module. apply (fn) [source] ¶ Applies fn recursively to every submodule (as returned by .children()) as well as self. Typical use includes initializing the parameters of a model (see also torch.nn.init). Parameters. fn (Module-> None) – function to be applied to each submodule. Returns. self. Return ...

When it comes to Module , there is no clone method available so you can either use copy.deepcopy or create a new instance of the model and ...

Jan 22, 2020 · Summary: Previously we have `clone` and `clone_instance`, where `clone` will clone both type and value, and `clone_instance` only clone the value, both of them are shallow copies. We need to re-evaluate whether we should expose them as a user facing API.

torch.clone. Returns a copy of input. This function is differentiable, so gradients will flow back from the result of this operation to input. To create a tensor without an autograd relationship to input see detach (). input ( Tensor) – the input tensor. memory_format ( torch.memory_format, optional) – the desired memory format of returned ...

Module¶ class torch.nn. Module [source] ¶. Base class for all neural network modules. Your models should also subclass this class. Modules can also contain other Modules, allowing to nest them in a tree structure.

Feb 14, 2017 · Hi, copy.deepcopy(model) works fine for me in previous PyTorch versions, but as I’m migrating to version 0.4.0, it seems to break. ... Clone a Module? ptrblck ...

22.01.2020 · @jerryzh168: I feel that clone() is not well-defined and we are receiving many issues due to it not behaving as people expect.. I propose we follow more closely Python's scheme to avoid confusion: Implement a deepCopy() method on script::Module that clones all state of the module recursively. This includes cloning all tensors. The type should not be cloned; the new …

I have a function that accepts a Module as input, and trains it. ... I am planning to just deep copy the trained model and save it somewhere ...

ModuleList¶ class torch.nn. ModuleList (modules = None) [source] ¶. Holds submodules in a list. ModuleList can be indexed like a regular Python list, but modules it contains are properly registered, and will be visible by all Module methods.. Parameters. modules (iterable, optional) – an iterable of modules to add. Example:
