numpy version issue while installing via pip

Ubuntu 16.04.6 LTS, Python 3.7.3 (pyenv).

Using pip install gluonts in a clean environment will get version conflict error about. It will try to install numpy 1.16.4 first:

Collecting numpy>=1.14.0 (from gluonts)
  Downloading https://files.pythonhosted.org/packages/fc/d1/45be1144b03b6b1e24f9a924f23f66b4ad030d834ad31fb9e5581bd328af/numpy-1.16.4-cp37-cp37m-manylinux1_x86_64.whl (17.3MB)

And later mxnet gives version conflict error:

ERROR: mxnet 1.4.1 has requirement numpy<1.15.0,>=1.8.2, but you'll have numpy 1.16.4 which is incompatible.

Workaround is to run pip install mxnet after pip install gluonts to let pip downupgrade numpy:

$ pip install mxnet

If it’s not easy to fix, maybe add some instructions into README.md.

@gslin thanks for reporting this, we’ve fixed the NumPy version and the problem should not occur on the next tagged release.

@lostella hello, gluonts python package was just updated on July 23, seems this numpy version problem is still here.

@aalexandrov Hello Alex,

Yes, the only solution at this moment is to downgrade catboost with numpy==0.14, and it works. I am just wondering whether it is possible to have gluonts and mxnet compatible with latest version of numpy in the future so there would not be any conflict between the latestest version of mxnet, gluonts and other py packages.
the installation cannot be completed, the warning message is the only thing shows up, no error message. This happens after me manually editing requirement.txt to numpy >=1.14.*.

Anyway, this problem is solved, thanks for help 😃
