Once installed, Catalyst can easily be updated as a +``pip`` package regardless of the environemnt used for installation. Make sure +you activate your environment first as you did in your first install, and then +execute: + +.. code-block:: bash + + $ pip uninstall enigma-catalyst + $ pip install enigma-catalyst + +Alternatively, you could update Catalyst issuing the following command: + +.. code-block:: bash + + $ pip install -U enigma-catalyst + +but this command will also upgrade all the Catalyst dependencies to the latest +versions available, and may have unexpected side effects if a newer version of a +dependency inadvertently breaks some functionality that Catalyst relies on. +Thus, the first method is the recommended one. + Getting Help ------------ From a58fa21234cf18a18457d60eefbdca7badf65d18 Mon Sep 17 00:00:00 2001 From: Frederic Fortier Date: Thu, 18 Jan 2018 19:26:07 -0500 Subject: [PATCH 37/43] BLD: fixed benchmark loader --- catalyst/exchange/exchange.py | 2 -- 1 file changed, 2 deletions(-) diff --git a/catalyst/exchange/exchange.py b/catalyst/exchange/exchange.py index 4ef2cc7a..bd6ce238 100644 --- a/catalyst/exchange/exchange.py +++ b/catalyst/exchange/exchange.py @@ -586,7 +586,6 @@ class Exchange: frequency, data_frequency ) adj_bar_count = candle_size * bar_count -
