Cannot convert a symbolic Tensor (simple_rnn/strided_slice:0) to a numpy array. 报错（解决方法）

1.报错问题：（来自《Python深度学习》P164-165）

在运行以下代码的时候，报错：Cannot convert a symbolic Tensor (simple_rnn/strided_slice:0) to a numpy array. This error may indicate that you're trying to pass a Tensor to a NumPy call, which is not supported.

# 只返回最后一个时间步的输出from tensorflow.keras.models import Sequential
from tensorflow.keras.layers import Embedding, SimpleRNNmodel = Sequential()
model.add(Embedding(10000, 32))
model.add(SimpleRNN(32))
model.summary()

2. 解决方法：

查了一下，当时用的numpy版本：

疑问：会不会是 numpy版本太高了导致的？

于是，正好有个低版本的虚拟环境，其numpy版本为：

重新运行了上述代码，发现有Warning，但无伤大雅，可以运行：

WARNING:tensorflow:From D:\QLDownload\AnacondaDon\envs\python37\lib\site-packages\tensorflow\python\keras\initializers.py:119: calling RandomUniform.__init__ (from tensorflow.python.ops.init_ops) with dtype is deprecated and will be removed in a future version.
Instructions for updating:
Call initializer instance with the dtype argument instead of passing it to the constructor

解决Cannot convert a symbolic Tensor (lstm/strided_slice:0) to a numpy array.
pip install numpy==1.18.1
NotImplementedError: Cannot convert a symbolic Tensor (lstm/strided_slice:0) to a numpy array.
这是numpy版本与tensorflow版本不兼容导致的 tensorflow2.2 + numpy1.19.2表示没问题.
NotImplementedError: Cannot convert a symbolic Tensor (while/add_8:0) to a numpy array.
代码: 报错如下: 将np.power()改成**就解决了,猜测是numpy包的原因
