Subject: [PATCH] fix(layers): avoid duplicate enable_proxy_error kwarg in
 make_quant_linear
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When loading models saved from the algorithm branch, layer_conf may
contain enable_proxy_error from the saved config. Passing it again as
an explicit kwarg caused TypeError: got multiple values for keyword
argument 'enable_proxy_error'.

Fixes #196.
