J'utilise Ubuntu 16.04. J'ai installé anaconda en utilisant bash ~/Downloads/Anaconda3-5.1.0-Linux-x86_64.sh
.
Puis je crée un nouvel environnement conda create -n python35 python=3.5 anaconda
Puis j'active conda activate python35
. Ensuite, je lance python en tapant python
, mais il indique toujours que j'utilise python 2.7.
Modifier:

C'est pour cette raison que vous avez cette ligne dans votre fichier .bashrc
.
alias python=python2.7
Supprimez cette ligne avec cette commande:
sed -i.bak '/python=python2.7/d' ~/.bashrc
Et puis exécutez cette commande:
source ~/.bashrc
