numpy version issue while installing via pip about gluonts HOT 9 CLOSED

@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.

Maybe its best to just set an upper bound to the allowed numpy version to numpy>=1.14.0,<1.15.0 in the requirements/requirements.txt file.

@whyxiang: could you give this a shot on a cloned repo points to the current master and applies the suggested fix? The install command should be

pip install ".[shell]" 

from gluonts.

FYI, am I the only one that thinks this is (mildly) unexpected - pip should be able to handle this case automatically by resolving all dependencies upfront and computing the intersection of allowed version ranges for dependencies defined through multiple paths.

Hi Alex, I install glutonts 0.3.0 manually by pip install the .whl file downloaded from pypi.org

I am installing both catboost and gluonts packages, catboost requires numpy >=1.15.0 but gluonts requires numpy ==1.14.*

hello Alex, I pip install using the gluonts-0.3.0.tar.gz downloaded from pypi.org
After extracting files from .tar.gz, I manually edited requirements/requirements.txt file with numpy>=1.14.*, then just python setup.py install

However, the installation cannot be completed. The following warning message shows up, and the installation never moves on
WARNING:root:Package 'sphinx' not found. You will not be able to build the docs.

It seems that the issue is present not just in gluonts==0.3.0 but also in mxnet==1.4.1.

Both packages require numpy<1.15.0, whereas catboost==0.16 requires numpy>=1.16.0, Strictly speaking, this makes catboost==0.16 incompatible with gluonts==0.3.0 or mxnet==1.4.1.

The only solution I can suggest is to use catboost==0.14 or lower.

This is just a warning, it does not mean that the package is not installed.

Hello Alex,

1. 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.

2. 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 :)
