[Ubuntu] `Python.import("numpy")` fails in the REPL about swift HOT 5 CLOSED

➜  swift usr/bin/swift -Iusr/lib/swift/clang/include
Welcome to Swift version 4.2-dev (LLVM 04bdb56f3d, Clang b44dbbdf44, Swift 2347c83692). Type :help for assistance.
  1> import Python
  2> Python.import("os")
$R0: Python.PyValue = <module 'os' from '/usr/lib/python2.7/os.pyc'>
  3> Python.import("numpy")
Fatal error: 'try!' expression unexpectedly raised an error: exception: 
Importing the multiarray numpy extension module failed.  Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control).  Otherwise reinstall numpy.

Original error was: /home/phuc/.local/lib/python2.7/site-packages/numpy/core/multiarray.so: undefined symbol: PyExc_UserWarning
: file /home/swift-build/swift/stdlib/public/core/ErrorType.swift, line 184
