Our first, thank you very much for the answer, I was already discouraged from getting any help and even considering using another framework. I created another test environment with virtualenv and when I went to install I got the following error:
tensorflow 1.10.0 has requirement numpy <= 1.14.5,> = 1.13.3, but you’ll have numpy 1.15.2 which is incompatible.
The problem is that when I change the numpy version I edit the dependency of the tensorflow, but rasa_core break. I do not know what to do, I thought the installation was simpler.
