How to pass an array from C to an embedded python script

亡梦爱人 提交于 2019-11-28 06:05:00
I am running to some problems and would like some help. I have a piece code, which is used to embed a python script. This python script contains a function which will expect to receive an array as an argument (in this case I am using numpy array within the python script). I would like to know how can I pass an array from C to the embedded python script as an argument for the function within the script. More specifically can someone show me a simple example of this. Really, the best answer here is probably to use numpy arrays exclusively, even from your C code. But if that's not possible, then

PyTorch / Gensim - How to load pre-trained word embeddings

隐身守侯 提交于 2019-11-28 05:58:53
I want to load a pre-trained word2vec embedding with gensim into a PyTorch embedding layer. So my question is, how do I get the embedding weights loaded by gensim into the PyTorch embedding layer. Thanks in Advance! I just wanted to report my findings about loading a gensim embedding with PyTorch. Solution for PyTorch 0.4.0 and newer: From v0.4.0 there is a new function from_pretrained() which makes loading an embedding very comfortable. Here is an example from the documentation. >> # FloatTensor containing pretrained weights >> weight = torch.FloatTensor([[1, 2.3, 3], [4, 5.1, 6.3]]) >>

How to convert a C string (char array) into a Python string when there are non-ASCII characters in the string?

拜拜、爱过 提交于 2019-11-28 03:34:55
问题 I have embedded a Python interpreter in a C program. Suppose the C program reads some bytes from a file into a char array and learns (somehow) that the bytes represent text with a certain encoding (e.g., ISO 8859-1, Windows-1252, or UTF-8). How do I decode the contents of this char array into a Python string? The Python string should in general be of type unicode —for instance, a 0x93 in Windows-1252 encoded input becomes a u'\u0201c' . I have attempted to use PyString_Decode , but it always

Embedding binary video data in a swf file

十年热恋 提交于 2019-11-28 01:50:20
问题 Is it possible to play video from data that has been embedded in a swf at compile time (with the [Embed] metatag)? The "Import Video->Embed" feature provided by Flash CS3 etc. is not acceptable because it has many severe limitations (including sound synchronization issues, a maximum number of frames, and other caveats) I'm interested in being able to bundle flv video data in a swf (along with other assets), which will be played by an AIR application. I don't think it can be done. Anyone

How to quickly and easily embed fonts in winforms app in C#

寵の児 提交于 2019-11-27 18:31:54
This is probably noob territory but what the heck: I want to embed fonts in my winforms application so that I don't have to worry about them being installed on the machine. I've searched a bit on the MSDN site and found a few hints about using native Windows API calls, for instance Michael Caplans (sp?) tutorial linked to by Scott Hanselman. Now, do I really have to go through all that trouble? Can't I just use the resource part of my app? If not I'll probably go the installing route. In that case, can I do that programmatically? By just copying the font file to the Windows\Fonts folder? Edit:

Embedding instead of inheritance in Go

What is your opinion of this design decision? What advantages does it have and what disadvantages? Links: Embedding description In a comment, you wondered if the embedding idea was enough to "replace inheritance completely". I would say the answer to that question is "yes". A few years ago I played very briefly with a Tcl OO system called Snit , which used composition and delegation to the exclusion of inheritance. Snit is still vastly different from Go's approach, but in that one respect they have some common philosophical ground. It's a mechanism for joining together pieces of functionality

How to embed LLVM assembly or intrinsics in C program with Clang?

核能气质少年 提交于 2019-11-27 16:26:51
问题 C compilers allows to embed assembly code in a C program. I am pretty sure that Clang should allow embedding LLVM assembly or intrinsic code in C program. How can I embed LLVM assembly in C code? 回答1: Right now you can't. You can, however, write an LLVM assembly function separately in its own file, mark it as alwaysinline , then compile it with the rest of your files - this should get you the same result. See this related question on how to first compile your C files to IR and then link them

How to perform “shell” icon embedding in Visual Studio 2010?

梦想的初衷 提交于 2019-11-27 15:51:35
As far as I can tell, there have been (at least?) three types of icon embedding. There's the original style used by shell32.dll and friends, .NET's embedding, and the new type that WPF uses. I'm looking for how to perform the first one, as I want to have a few other icons available as resources for a jumplist, which can only accept that style. However, I can't figure out how to embed in this style, only the other two. How do I do this? All the results I find on google, etc are for adding icons to ResX files or similar. I never heard the term "icon embedding" before. If you are talking about

Ensuring embedded structs implement interface without introducing ambiguity

﹥>﹥吖頭↗ 提交于 2019-11-27 15:25:13
I'm trying to clean up my code base by doing a better job defining interfaces and using embedded structs to reuse functionality. In my case I have many entity types that can be linked to various objects. I want to define interfaces that capture the requirements and structs that implement the interfaces which can then be embedded into the entities. // All entities implement this interface type Entity interface { Identifier() Type() } // Interface for entities that can link Foos type FooLinker interface { LinkFoo() } type FooLinkerEntity struct { Foo []*Foo } func (f *FooLinkerEntity) LinkFoo()

What is the idiomatic way in Go to create a complex hierarchy of structs?

落花浮王杯 提交于 2019-11-27 14:29:31
I am writing an interpreter in Go and I am looking for the idiomatic way to store the AST. I read the Go compiler source code and it seems they used interfaces with an empty method to represent the AST. For example, we have the following hierarchy, Object --Immovable ----Building ----Mountain --Movable ----Car ----Bike This is how the above hierarchy is implemented in the "empty method" way. type Object interface { object() } type Immovable interface { Object immovable() } type Building struct { ... } type Mountain struct { ... } type Movable interface { Object movable() } type Car struct { ..
