[scikit-learn] Can I install Python ML library such as XGBoost without pip?

[C W]

Update:

It seems I've already installed XGBoost before. But, I get the following
error:

>>> import xgboost
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File
"/Users/mike/opt/miniconda3/lib/python3.8/site-packages/xgboost/__init__.py",
line 9, in <module>
    from .core import DMatrix, DeviceQuantileDMatrix, Booster
  File
"/Users/mike/opt/miniconda3/lib/python3.8/site-packages/xgboost/core.py",
line 174, in <module>
    _LIB = _load_lib()
  File
"/Users/mike/opt/miniconda3/lib/python3.8/site-packages/xgboost/core.py",
line 157, in _load_lib
    raise XGBoostError(
xgboost.core.XGBoostError: XGBoost Library (libxgboost.dylib) could not be
loaded.
Likely causes:
  * OpenMP runtime is not installed (vcomp140.dll or libgomp-1.dll for
Windows, libomp.dylib for Mac OSX, libgomp.so for Linux and other UNIX-like
OSes). Mac OSX users: Run `brew install libomp` to install OpenMP runtime.
  * You are running 32-bit Python on a 64-bit OS
Error message(s):
['dlopen(/Users/mike/opt/miniconda3/lib/python3.8/site-packages/xgboost/lib/libxgboost.dylib,
6): Library not loaded: /usr/local/opt/libomp/lib/libomp.dylib\n
 Referenced from:
/Users/mike/opt/miniconda3/lib/python3.8/site-packages/xgboost/lib/libxgboost.dylib\n
 Reason: image not found']

It seems OpenMP runtime the one I am missing. I can install by running
> brew install libomp

But, I don't have brew on this computer. Any work around?

Thanks!
