kandi X-RAY | cc Summary
First quick intro to ZMQ messages: ZMQ transports blobs, with header that specifies length for the blob and whether it is last blob or not. So one logical message can contain one or more blobs. ZMQ calls it "multipart message". Simple ZMQ request-reply pattern, implemented by zmq.REP, zmq.XREP sockets, is to add additional blob at the start of the message on each hop, which contains socket id from where the message came from. So on reply the message can be routed by over several hops, each one removes the socket id when it sends it further. Empty part ('') separates such socket ids from actual body parts.

QUESTION
What's the XLA class XlaBuilder for? The docs describe its interface but don't provide a motivation.
The presentation in the docs, and indeed the comment above XlaBuilder in the source code
ANSWER
Answered 2021-Dec-15 at 01:32XlaBuilder is the C++ API for building up XLA computations -- conceptually this is like building up a function, full of various operations, that you could execute over and over again on different input data.
Some background, XLA serves as an abstraction layer for creating executable blobs that run on various target accelerators (CPU, GPU, TPU, IPU, ...), conceptually kind of an "accelerator virtual machine" with conceptual similarities to earlier systems like PeakStream or the line of work that led to ArBB.
The XlaBuilder is a way to enqueue operations into a "computation" (similar to a function) that you want to run against the various set of accelerators that XLA can target. The operations at this level are often referred to as "High Level Operations" (HLOs).
The returned XlaOp represents the result of the operation you've just enqueued. (Aside/nerdery: this is a classic technique used in "builder" APIs that represent the program in "Static Single Assignment" form under the hood, the operation itself and the result of the operation can be unified as one concept!)
XLA computations are very similar to functions, so you can think of what you're doing with an XlaBuilder like building up a function. (Aside: they're called "computations" because they do a little bit more than a straightforward function -- conceptually they are coroutines that can talk to an external "host" world and also talk to each other via networking facilities.)
So the fact XlaOps can't be used across XlaBuilders may make more sense with that context -- in the same way that when building up a function you can't grab intermediate results in the internals of other functions, you have to compose them with function calls / parameters. In XlaBuilder you can Call another built computation, which is a reason you might use multiple builders.
As you note, you can choose to inline everything into one "mega builder", but often programs are structured as functions that get composed together, and ultimately get called from a few different "entry points". XLA currently aggressively specializes for the entry points it sees API users using, but this is a design artifact similar to inlining decisions, XLA can conceptually reuse computations built up / invoked from multiple callers if it thought that was the right thing to do. Usually it's most natural to enqueue things into XLA however is convenient for your description from the "outside world", and allow XLA to inline and aggressively specialize the "entry point" computations you've built up as you execute them, in Just-in-Time compilation fashion.

I'm using Mac M1 and I've just upgraded to Node 14.17.6LTS.
I tried to rebuild better_sqlite3 (7.4.3) using with electron builder (22.11.7) and I'm getting the following errors:
no member named 'GetContents' in 'v8::ArrayBuffer'
Any ideas how to solve this? Thanks in advance!

ANSWER
Answered 2021-Sep-23 at 01:15I'm using Mac M1 and I've just upgraded to Node 14.17.6LTS.
An interesting choice, given that Node 16 officially introduced M1 support.
no member named 'GetContents' in 'v8::ArrayBuffer'
See this doc. In short, GetContents was replaced by GetBackingStore in late 2019. Being a compatibility layer, nan adapted to this in early 2020.
So you'll probably have to ensure that the versions of all involved packages (Node, nan, electron, ...) match each other (in the sense of having been released around the same time and targeting each other).

I am implementing a simple chatbot using keras and WebSockets. I now have a model that can make a prediction about the user input and send the according answer.
When I do it through command line it works fine, however when I try to send the answer through my WebSocket, the WebSocket doesn't even start anymore.
Here is my working WebSocket code:
...ANSWER
Answered 2022-Feb-16 at 19:53There is no problem with your websocket route. Could you please share how you are triggering this route? Websocket is a different protocol and I'm suspecting that you are using a HTTP client to test websocket. For example in Postman:
HTTP requests are different than websocket requests. So, you should use appropriate client to test websocket.
QUESTION
I have a Python 3 application running on CentOS Linux 7.7 executing SSH commands against remote hosts. It works properly but today I encountered an odd error executing a command against a "new" remote server (server based on RHEL 6.10):
encountered RSA key, expected OPENSSH key
Executing the same command from the system shell (using the same private key of course) works perfectly fine.
On the remote server I discovered in /var/log/secure that when SSH connection and commands are issued from the source server with Python (using Paramiko) sshd complains about unsupported public key algorithm:
userauth_pubkey: unsupported public key algorithm: rsa-sha2-512
Note that target servers with higher RHEL/CentOS like 7.x don't encounter the issue.
It seems like Paramiko picks/offers the wrong algorithm when negotiating with the remote server when on the contrary SSH shell performs the negotiation properly in the context of this "old" target server. How to get the Python program to work as expected?

...ANSWER
Answered 2022-Jan-13 at 14:49Imo, it's a bug in Paramiko. It does not handle correctly absence of server-sig-algs extension on the server side.
Try disabling rsa-sha2-* on Paramiko side altogether:

I am trying to call C functions inside python and discovered the ctypes library (I'm fairly new to both C and python's ctypes), motive (however stupid) is to make python code's speed on par with c++ or close enough on a competitive website. I have written the C code and made a shared library with the following command cc -fPIC -shared -o lib.so test.c and imported it into python with ctypes using the following code:

I am new to queue & threads kindly help with the below code , here I am trying to execute the function hd , I need to run the function multiple times but only after a single run has been completed
...ANSWER
Answered 2021-Dec-27 at 07:53You can use a Semaphore for your purposes
A semaphore manages an internal counter which is decremented by each acquire() call and incremented by each release() call. The counter can never go below zero; when acquire() finds that it is zero, it blocks, waiting until some other thread calls release().
A default value of Semaphore is 1,
class threading.Semaphore(value=1)
so only one thread would be active at once:
