poetry goes into infinite loop when trying to install allennlp

• OS version and name: Arch Linux
• Poetry version: 0.12.10

Issue

when trying to install allennlp with poetry add allennlp (0.8.0) it seems to go into an infinite loop of resolving dependencies (20+ minutes, sometimes failing with HTTP connection errors after a while).

Previously (allennlp 0.7.2) poetry completely failed to install allennlp due to too strict dependencies (see here).

Hi, I faced the same issue too. Here is the log if I ran poetry add allennlp -vvvv as Gist:

It seems that the installation of the botocore package has failed and is in an infinite loop. The issue here is that the error 1: conflict: no versions of botocore match >1.16.12,<1.17.0 (this line) is displayed, even though the condition derived: botocore (>=1.16.12,<1.17.0) (this line) is specified.

I found that I could avoid this infinite loop by first adding boto3 with poetry add boto3 and then running poetry add allennlp. I don’t think this is a good solution. Any ideas on how to solve this issue?

@gvskalyan that issue was closed in favor of https://github.com/allenai/allennlp/issues/2280. We’re not familiar with poetry but we would welcome PRs that make AllenNLP’s dependencies more compatible with poetry.
