 # For a complete list of dependencies, please read:
 # https://gitlab.idiap.ch/bob/bob/wikis/Dependencies

+# the dependencies that come before anaconda are being pulled and pinned using
+# anaconda. When you update to a new version of anaconda make sure the
+# dependencies are still in the newer version of anaconda. If they are not there
+# anymore, you need to pin them if we still need them. Otherwise, remove them
