kandi X-RAY | ppx Summary

ppx is a Rust library typically used in Utilities, Parser applications. ppx has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

PPX is a cross-platform Probabilistic Programming eXecution protocol and API based on flatbuffers. It is intended as an open interoperability protocol between models and inference engines implemented in different probabilistic programming languages. Probabilistic programming is about the execution probabilistic models under the control of inference engines, and PPX allows the model and the inference engine to be. PPX is inspired by ONNX, the Open Neural Network Exchange project allowing interoperability between major deep learning frameworks.

AMD RAPL power domains relations

Asked 2022-Mar-31 at 07:14

Intel CPUs provide power monitoring via RAPL for several power domains - PKG, DRAM, PPx, Platform. Many sources describe these power domains and their relations, nice figure is in Khan, K. et al. “RAPL in Action.” ACM Transactions on Modeling and Performance Evaluation of Computing Systems (TOMPECS) 3 (2018): 1 - 26.

AMD CPUs also have RAPL interface for power monitoring (as far as I know) PKG and Core domains, however I have not found any source presenting relations of these power domains. Does PKG domain include Core domains? One would expect that it does, but it is just an assumption.

Since there is a 1:1 mapping of package and core energy consumption for workloads that only use core ressources [1, Fig. 9b] this is very likely.

QUESTION

Shader working on my laptop, but not on my desktop

Asked 2022-Feb-25 at 10:47

I already posted this question on unity answers yesterday, but maybe anyone here can help? I've been trying to do some stuff that involves getting an image from a native plugin (in the form of a .dll file). I load the image data into a native buffer and then push that to the gpu in the form of a structured compute buffer. From there, I display the image using a shader (basically just doing something like uint idx = x + y * width to get the correct index). And this works great on my laptop (ignore the low resolution, I lowered it to be able to inspect the values for each pixel; this is exactly how it's supposed to look).

But when I try it on my desktop, all I get is this mess:

It's clearly displaying something, I'm almost able to make out contours of the text (it doesn't seem like I'm just getting random noise). But I can't seem to work out what's wrong here.

So far I've tried:

syncing the code across the two devices (it's excactly the same)
changing the unity version (tried 2020.3.26f1 and 2021.2.12f on both machines)
updating the graphics drivers
checking the directx version (DirectX 12 on both)
changing the editor game window resolution
comparing the contents of the buffer (the ComputeBuffer.GetData method is getting the same completely valid values on both machines)
building the project on both machines (both builds are working on my laptop and broken on my desktop)

Especially the last point really confused me. I'm running the same executable on both machines and it's working on my laptop with integrated graphics (not sure wether that could be relevant) but not on my desktop with a more modern dedicated gpu? The only idea I have left is that there might be some kind of optimization going on with my desktop's amd gpu that's not happening on my laptop's intel gpu. Any ideas on what I could try in the radeon software? Maybe it could even be some sort of bug (with unity or with my graphics driver)?

I'd be more than happy about any ideas on what could be the problem here (cause I have no clue at this point). And sorry if my grammar is a bit off at times, not a native speaker.

EDIT: Here's the shader I use to display the image.

QUESTION

when are modules redeclared vs aliased?

Asked 2021-Oct-21 at 20:52

I have a very hard time understanding in OCaml when modules and types are aliased versus redeclared.

For example, to use a module A in a file x.ml it seems like I have several path:

open X.A, not great as I open all of the thing
module A = X.A, am I redeclaring here? Will this create all sorts of problem?
use https://github.com/johnyob/ppx-open to bring a Rust-flavored use X::A
module B with A := A the destructive module substitution, but by doing that I lose access to the module A

Am I missing something?

...

ANSWER

Answered 2021-Oct-21 at 20:52

In open A nothing is defined or declared, this module expression just allows you to use elements from the opened module without referencing the module name. This is a pure namespacing operation that has no reflection in runtime. In other words, it only affects the typing environment.

In module A = X.A you're defining (since 4.02) a module alias. So nothing is redeclared and A, as well as all its components, could be used in the same place where X.A and its components are expected.

The ppx_open extension gives you better control over what you want to alias in the current module. In the end, it rewrites to

OCaml serializing a (no args) variant as a "string enum" (via Yojson)

ANSWER

Answered 2021-Jun-06 at 18:50

Regarding the last error, it's because OCaml requires a 'stable path' to types inside modules so it can refer to them. A stable path is a named path to a type, e.g. Fruit.t.

By contrast, StrEnum(struct type t = ... end).t is not a stable path because the type t is referencing a type t in the module literal which does not have a name.

Long story short, you basically can't skip defining the variant module separately. But it's simple to do it in two steps:

Scipy optimize unable to find the correct results

Asked 2021-Feb-14 at 12:14

I am trying to use scipy.optimize.minimize to fit parameters for a multivariate function, however, regardless of how many noise free data points I am providing to the optimizer, the optimizer could not converge to a correct (or close) answer.

I wonder if there is a mistake in the way I am using the optimizer but I have been scratching my head to find the mistake. I would appreciate any advice or guesses, thanks!

ANSWER

Answered 2021-Feb-14 at 12:14

You are solving least squares problem, but trying to optimize it using a solver that minimizes a scalar function. While it can possibly solve the problem, it does so very inefficiently. It can require much more iterations or can fail to converge at all.

The better way is to use least_squares instead of minimize.

For it to work properly you should modify error function by returning 1D numpy array instead of a scalar:

QUESTION

Why is the ##. operator needed in js_of_ocaml?

Asked 2020-May-25 at 06:38

Not sure why all those operators are needed. What's the rationale? Why is not the regular OCaml object syntax enough?

...

ANSWER

Answered 2020-May-25 at 06:38

OCaml objects do not have properties. If you write obj#m, you are calling method m on object obj. If you write obj#m := e, you are again calling method m on object obj and it returns a value of type 'e ref, which is then passed to operator (:=).

Hence operator ##., which is just syntactic sugar for calling Js.Unsafe.get, respectively Js.Unsafe.set. (Similarly, obj##m x y is syntactic sugar for Js.Unsafe.meth_call obj "m" [|x; y|].)

Rather than modifying the OCaml compiler in depth to actually map Javascript objects to OCaml ones and correctly recognize getters/setters, JSOO is a thin layer that depends on OCaml objects only for typing Javascript ones and ignores them entirely for execution.
