Hi all, I am a new user of kwant and I have some troubles in installing kwant on the Enthought Canopy environment. I have always used this environment for my numerical work with Python and it is annoying to change it. The downside is that it only supports Python 2.7 and not the latest Python 3.x. This is the source of problems. I follow the instructions in this webpage <https://support.enthought.com/hc/en-us/articles/204469690-Installing-package...>. Essentially they ask to run the command 'pip install kwant' within their Canopy Terminal. If I try to do this I get the following error message """"" (Canopy 64bit) peottas1@penrose:/m/home/home5/50/peottas1/unix$ pip install kwant Collecting kwant Downloading kwant-1.2.2.tar.gz (820kB) 100% |████████████████████████████████| 829kB 996kB/s Complete output from command python setup.py egg_info: This version of Kwant requires Python 3.4 or above. Kwant 1.1 is the last version to support Python 2. ---------------------------------------- Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-VoZTHV/kwant/ """ According to the install instructions in the Kwant homepage the pip command should automatically install the Python 2 version, while the command pip3 should install the Python 3 version. However this does not seem the case. Moreover if I try to do a search with pip I get the following """ (Canopy 64bit) peottas1@penrose:/m/home/home5/50/peottas1/unix$ pip search kwant kwant (1.2.2) - Package for numerical quantum transport calculations (Python 3 version) """ so it seems that only kwant-1.2.2 is available for download. On the contrary in the webpage "https://pypi.python.org/pypi/kwant" both version 1.1.2 and 1.2.2 are available. Can you give me some hint on how to solve the problem? Best, Sebastiano
