How can I install Auto-PyTorch on Windows 10 from requirements.txt?
I have been trying to install Auto-PyTorch, an automatic Neural Network tuning system (more info about installation here: https://github.com/automl/Auto-PyTorch), in a Windows 10 system. The installation steps are as follow:
$ cd install/path
$ git clone https://github.com/automl/Auto-PyTorch.git
$ cd Auto-PyTorch
$ cat requirements.txt | xargs -n 1 -L 1 pip install
$ python setup.py install

However, I can't get around the following line of code:
cat requirements.txt | xargs -n 1 -L 1 pip install

Once I get there, the following Windows PowerShell error is raised:
xargs : The term 'xargs' is not recognized as the name of a cmdlet, function, script file, or 

operable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:86
+ ... read.CurrentUICulture = 'en-US'; cat requirements.txt | xargs -n 1 -L ...
+                                                             ~~~~~
    + CategoryInfo          : ObjectNotFound: (xargs:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

Note that I passed the following line of code so that the error is thrown in English (I am Spanish):
[Threading.Thread]::CurrentThread.CurrentUICulture = 'en-US'; cat requirements.txt | xargs -n 1 -L 1 pip install

I'm not an expert on PowerShell, so I would greatly appreciate your help.
Best regards!

Since you're running on Windows PowerShell, only command-line utilities natively available on Windows can be assumed to be available - and xargs, a Unix utility, is not among them.
(While git also isn't natively available, it looks like you've already installed it).
Here's a translation of your code into native PowerShell code (note that cd is a built-in alias for Set-Location, and, on Windows only, cat is a built-in alias for Get-Content; % is a built-in alias for the ForEach-Object cmdlet):
Set-Location install/path
git clone https://github.com/automl/Auto-PyTorch.git
Set-Location Auto-PyTorch
Get-Content requirements.txt | % { pip install $_ }
python setup.py install
