CNTK Python one\u热编码无原型

Question

我试着用cntk.utils.one\u热具体如下：

# actions is numpy array of shape (32, 1) and _output_shape is 6
actions = one_hot(actions, self._output_shape)

但它抱怨说数字浮点数32不支持。你知道吗

我试图转换为Python列表：

actions = one_hot(list(actions), self._output_shape)

我得到以下错误：

  File "/home/malmo_user/Workspace/malmo-collab/msrc-rl/model/backend/cntk.py", line 213, in train
    actions = one_hot(list(actions), self._output_shape)
  File "/home/malmo_user/anaconda3/envs/cntk-py34/lib/python3.4/site-packages/cntk/utils/swig_helper.py", line 58, in wrapper
    result = f(*args, **kwds)
  File "/home/malmo_user/anaconda3/envs/cntk-py34/lib/python3.4/site-packages/cntk/utils/__init__.py", line 76, in one_hot
    value = cntk_py.Value.create_one_hot_float(num_classes, batch, device, False)

    CNTK::Value::CNTK_Value_CreateOneHotFloat__SWIG_0(size_t,std::vector< std::vector< size_t,std::allocator< size_t > >,std::allocator< std::vector< size_t,std::allocator< size_t > > > > const &,CNTK::DeviceDescriptor const &)

Answer 1

输入一个热指数。它们必须是整数。试试看

actions.astype(int).tolist()
