xar | eXtensible ARchiver | REST library

I hope this message finds you well. I have worked on TwinCAT XAE for past couple of months. I have developed and tested my programs on my Development PC using TwinCAT XAE and Visual studio.

Now I want to shift my programs from my development PC to my Runtime PC (Windows) which is eventually going to be installed by the machine. I want some guidance regarding transfering my programs from XAE to XAR. In simple words I want to know how to get the .EXE file to run on the TwinCAT XAR.

I am also facing some configuration issues with XAR. Can you share any installation guide or prerequisites for the TwinCAT XAR software

I am estimating a model using the pyMC3 library in python. In my "real" model, there are four parameter arrays, two of which have over 170,000 parameters in them. Summarising this array of parameters is too computationally intensive on my computer. I have been trying to figure out if the summary function in arviz will allow me to only summarise one (or a small number) of parameters in the array. Below is a reprex where the same problem is present, though the model is a lot simpler. In the linear regression model below, the parameter array b has three parameters in it b[0], b[1], b[2]. I would like to know how to get the summary for just b[0] and b[1] or alternatively for just a single parameter, e.g., b[0].

I'm new to matplotlib and I can't set the axis labels for my plot. I also tried plt.xlabel("xlabel") and ax1.set(xlabel="Images") but both have failed. Any ideas?

I am trying to dynamically update a matplotlib from a .txt file that periodically updates.

For this, I used the following tutorial.

https://pythonprogramming.net/python-matplotlib-live-updating-graphs/

The .txt file looks like such

We are unable to distribute our sample app which uses our framework as well as our users can't. While archiving and distributing to AppStore, the app is rejected with the following message:

Invalid Bundle - One or more dynamic libraries that are referenced by your app are not present in the dylib search path. If your app contains bitcode, bitcode processing may have failed. Because of these errors, this build of your app will not be able to be submitted for review or placed on the App Store.

The framework contain the bitcode, or at least there's a BITCODE_GENERATION_MODE = bitcode build setting in our .xcconfig, which basically means, the Xcode will add -fembed-bitcode build flag to any clang invocation.

From here, we've started testing using Ad-Hoc builds, to speed up our trial and error attempts, which also fails while Rebuild from bitcode option is selected. Organiser shows the popup with the following contents:

I've been struggling with this error for 2 weeks & I tried almost all solutions available online. When trying to export adhoc ipa, I get the below error:

The interesting part here is the last Output:

On seeing llvm_prf_cnts & llvm_prf_data, I checked this apple guide and disabled code coverage and also GCC_INSTRUMENT_PROGRAM_FLOW_ARCS

We have Bitcode enabled and the same setup works in Xcode 11.

Can someone please shed some light on why this might be happening? Any leads would be much appreciated. Thanks.

In the process of learning Javascript. I have written a code which goes through an array and adds them to res array. It will also go through the nested arrays and add them element by element to res. I have used recursion for this. But after each nested array finishes I am getting a Circular added to res. Unable to find where the problem is.

I'm building a project which I wish to trigger some pre-installed behaviors inside my robot (which i downloaded from a developer). Understand that i can import content in behaviors (.xar) format into my current project. Any idea how can I extracting the installed behaviors from the robot to my PC?

Thanks
