次の定義を持つライブラリ (カフェ) があります。
class NetSpec(object):
def __init__(self):
super(NetSpec, self).__setattr__('tops', OrderedDict())
def __setattr__(self, name, value):
self.tops[name] = value
def __getattr__(self, name):
return self.tops[name]
def to_proto(self):
names = {v: k for k, v in self.tops.iteritems()}
autonames = {}
layers = OrderedDict()
for name, top in self.tops.iteritems():
top.fn._to_proto(layers, names, autonames)
net = caffe_pb2.NetParameter()
net.layer.extend(layers.values())
return net
を使用して呼び出そうとするとn = caffe.NetSpec()
、次のエラーが発生します。
File "../../python/caffe/layers.py", line 84, in __init__
super(NetSpec, self).__setattr__('tops', OrderedDict())
TypeError: must be type, not None
SO-9698614、SO- 576169 、SO -489269を確認しましたが、解決には至りませんでした。私のクラスは新しいタイプのクラスで、なぜ機能しないのかわかりませんでした。
完全なトレース:
