For the AMD process, we need to make clear to the visual studio that we use the AMD process and it should change the emulator behavior to our process.

First of all like I said we need to make sure the Virtual Machine Platform and Hyper-V are enabled because it’s necessary to run an android emulator in a visual studio.

Second, We need to make sure that Android Emulator Hypervisor Driver for AMD Processors is selected in the visual studio.

Android Emulator Hypervisor Driver for the AMD Processors:

I had to dig into the Rust repository history to get to this answer:

The yield has been replaced with isb in c064b6560b7c:

On arm64 we have seen on several databases that ISB (instruction synchronization barrier) is better to use than yield in a spin loop. The yield instruction is a nop. The isb instruction puts the processor to sleep for some short time. isb is a good equivalent to the pause instruction on x86.

[...]

So essentially, it uses the time it takes for an ISB to complete to pause the processor, so that it wastes less power.

Peter Cordes explained it nicely in one of his comments:

ISB SY doesn't stall for long, just saves a bit of power vs. spamming loads in a tight loop.

The idea of std::thread::hardware_concurrency is to tell you what kind of concurrency std::threads can experience. Since std::thread can only put threads into your default processor group, you will get the number of logical processors in your default processor group. This is not going to be greater than 64 on Windows unless you go to extreme measures.

"[A] system with 128 logical processors would have two processor groups with 64 processors in each group[.]"

"An application that requires the use of multiple groups so that it can run on more than 64 processors must explicitly determine where to run its threads and is responsible for setting the threads' processor affinities to the desired groups."

I found and tested in shorter toggle mechanism.

The configuration for Windows Feature:

• Windows Subsystem for Linux is installed.
• Windows Hypervisor Platform is installed.
• Hyper-V is installed.

If you need the Emulator, you only need to turn off Hypervisor + Restart. Run: bcdedit /set hypervisorlaunchtype off

If you need the Docker back, you can run the hypervisor hence disabling Emulator. Run: bcdedit /set hypervisorlaunchtype auto

You need to restart after setting Hypervisor

You cannot run both at the same time. Another forum worth checking in How about running docker? in my older answer below.

I think I solved this issue, tested to run from CMD / Android Studio and ran perfectly as before installing WSL. There are several step we go:

1. Removed Windows Subsystem for Linux
2. Removed Windows Hypervisor Platform
3. Removed Hyper-V

Here is my current setup:

I know after removing there are some odds because the AVD still get the same error as before and expected to get into WSL. I stumbled and found something when ran:

C:\Users\[NAME]\AppData\Local\Android\Sdk\emulator\emulator-check.exe accel

That command will check the current accel. It explains that the Hypervisor need to be set off and give specific help: run bcdedit /set hypervisorlaunchtype off.

After running the bcdedit, I restarted and all is reverted. Now I can run emulator both from CMD and Android Studio perfectly.

Sad truth, yeah you cannot run both pararel. There are several workaround in this forum:

How can I run both Docker and Android Studio Emulator on Windows?

Several option ranging from changing emulator, add & remove docker when in need using above step, created nested vm, etc. My personal choice right now is using another Emulator for the time being and removed docker for the latter.

Posting answer from comments for better visibility: Problem solved by reinstalling multipass and microk8s. Now it works.

tl;dr:

• A design limitation of Get-VHD prevents it from properly recognizing VHD paths that contain [ and ] (see bottom section for details).

• Workaround: Use short (8.3) file paths assuming the file-system supports them:

To find out processor number of cores using PowerShell

Get-WmiObject –class Win32_processor | ft NumberOfCores,NumberOfLogicalProcessors

To find out what is the number of threads running:

(Get-Process|Select-Object -ExpandProperty Threads).Count

I would recommend to create separate component called Question to avoid working with arrays of data and put state login inside. But if this is not possible I would do it this way:

As stated in the XGBoost Docs

Parameter tuning is a dark art in machine learning, the optimal parameters of a model can depend on many scenarios.

You asked for suggestions for your specific scenario, so here are some of mine.

1. Drop the dimensions booster from your hyperparameter search space. You probably want to go with the default booster 'gbtree'. If you are interested in the performance of a linear model you could just try linear or ridge regression, but don't bother with it during your XGBoost parameter tuning.
2. Drop the dimension base_score from your hyperparameter search space. This should not have much of an effect with sufficiently many boosting iterations (see XGB parameter docs).
3. Currently you have 3200 hyperparameter combinations in your grid. Expecting to find a good one by looking at 50 random ones might be a bit too optimistic. After dropping the booster and base_score dimensions you would be down to
