【问题描述】:
当我想使用 lstm 模型根据各种因素生成文本时,当我尝试使用我想要使用的数据时,我收到一个 Failed to convert a NumPy array to a Tensor (Unsupported object type list) 错误在接受输入时。以下是我给定的数据:
| state | district | month | rainfall | max_temp | min_temp | max_rh | min_rh | wind_speed | advice |
|---|---|---|---|---|---|---|---|---|---|
| [1] | [1] | 2 | 0.0 | 34.6 | 19.4 | 88.2 | 29.6 | 12.0 | [[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,0, 0, 0, 0, 0, 0, 10, 1, 11, 12, 13, 3, 4, 5],[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,0, 14, 15, 2, 16, 17, 6, 7, 2, 18, 19, 20, 8, 4],[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,0, 0, 0, 21, 9, 22, 5, 23, 24, 2, 25, 26, 6, 27]] |
| [2] | [2,3] | 2 | 0 | 35.2 | 16.6 | 29.4 | 11.2 | 3.6 | [[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 54, 55, 21, 56, 57, 3,22, 19, 58, 6, 59, 4, 60, 1, 61, 62, 23, 63, 23, 64], [ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 65, 7, 66, 2, 67, 68, 3, 69, 70], [ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 11, 12, 5, 13, 14, 9, 10, 5, 15, 16, 17, 2, 8], [ 0, 0, 0, 0, 0, 2, 71, 1, 72, 73, 74, 7, 75, 76, 77, 3, 20, 78, 18, 79, 1, 21, 80, 81, 3, 82, 83, 84, 6, 85]] |
我用来输入标签和数据的代码如下。
labels=data.pop('advices')
ds= tf.data.Dataset.from_tensor_slices((dict(data), labels))
我得到的错误如下。
TypeError: Could not build a TypeSpec for 0 [1]
1 [1]
2 [1]
3 [2, 3]
4 [2, 3]
Name: district, dtype: object with type Series
During handling of the above exception, another exception occurred:

97 ctx.ensure_initialized()

ValueError: Failed to convert a NumPy array to a Tensor (Unsupported object type list).
我是这个领域的新手,请有人帮助我。
【问题讨论】:
-
基于错误,我猜问题是你的数组中的元素不是标量而是序列本身
-
是的,就是这样。而且我知道我以后也会在建议列中得到同样的错误。我不知道如何解决它。

@Santosh Kumar:您是否已经找到了解决问题的方法,如果找到了,您会好心与我们分享吗?
