mxnet报错TypeError: type ＜class ‘mxnet.initializer.InitDesc‘＞ not supported

手动写mxnet预测代码对单个图像进行预测时，报错：

原因：传入参数的格式不对。使用下面的fc7_arg_params 这种形式就可以了。不要采用 fc7_overall = fc7_arg_params[‘fc7_weight’] 作为传入参数

# 要传入的参数读取
fc7_weight = mx.ndarray.load(fc7 + '-' + str(epoch) + '.bin')
fc7_arg_params = {'fc7_weight': fc7_weight[0]} # 正确的形式

# 传入参数并初始化
_initializer = mx.init.Normal(0.01)
fc7_mod.init_params(_initializer, arg_params=fc7_arg_params, aux_params={}, allow_missing=True,
                                force_init=False, allow_extra=False)
