Rasa: What is happening here?

[juanmariareina]

Hi all!

I'm trying to install RASA on Ubuntu 16.04.6

python3 is 3.6.8
And this is how I've installed pip3:

sudo apt-get install python3-pip

Then I do

pip3 install rasa-x --extra-index-url https://pypi.rasa.com/simple

And the installation process finishes with the following error:

Collecting tensorflow~=1.15.0 (from rasa~=1.4.0->rasa-x)
Could not find a version that satisfies the requirement tensorflow~=1.15.0 (from rasa~=1.4.0->rasa-x) (from versions: 0.12.1, 1.0.0, 1.0.1, 1.1.0rc0, 1.1.0rc1, 1.1.0rc2, 1.1.0, 1.2.0rc0, 1.2.0rc1, 1.2.0rc2, 1.2.0, 1.2.1, 1.3.0rc0, 1.3.0rc1, 1.3.0rc2, 1.3.0, 1.4.0rc0, 1.4.0rc1, 1.4.0, 1.4.1, 1.5.0rc0, 1.5.0rc1, 1.5.0, 1.5.1, 1.6.0rc0, 1.6.0rc1, 1.6.0, 1.7.0rc0, 1.7.0rc1, 1.7.0, 1.7.1, 1.8.0rc0, 1.8.0rc1, 1.8.0, 1.9.0rc0, 1.9.0rc1, 1.9.0rc2, 1.9.0, 1.10.0rc0, 1.10.0rc1, 1.10.0, 1.10.1, 1.11.0rc0, 1.11.0rc1, 1.11.0rc2, 1.11.0, 1.12.0rc0, 1.12.0rc1, 1.12.0rc2, 1.12.0, 1.12.2, 1.12.3, 1.13.0rc0, 1.13.0rc1, 1.13.0rc2, 1.13.1, 1.13.2, 1.14.0rc0, 1.14.0rc1, 1.14.0, 2.0.0a0, 2.0.0b0, 2.0.0b1)

You are using pip version 8.1.1, however version 19.3.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

I'm managing to fix it by myself. Next time I will be more patient

How did you fix it?

[aaronbriel]

Quick and dirty fix is to throw python-dateutil<2.8.1 in your requirements.txt.

@aaronbriel Thanks; I haven't thoroughly tested but that seems to make my project happy again. Do you know the root cause?

From what I found out, the issue is here: https://github.com/boto/botocore/issues/1872
