Tensorflow and Numpy NotImplementedError: Cannot convert a symbolic Tensor (lstm_2/strided_slice:0) to a numpy array is an error which occurs when numpy is not compatible with Tensorflow or even python.
I will explain why this error takes place and how to fix it, while also trying to add other solutions that could solve the error.
Exploring Tensorflow and Numpy NotImplementedError Cannot convert a symbolic Tensor
This is an error which occurs when numpy is not compatible with Tensorflow or even python.
Please double check so you can avoid mixing between different errors. The error message should look like the error message bellow.

Bellow we will take care of the error using multiple possible solutions according to your needs.
Solution 1 : Downgrade numpy using conda or pip or Downgrade Python instead
We have established the fact that the error occurs when numpy is not compatible with Tensorflow or with python.
There are many ways to solve the issue, if you want to keep your version of numpy you can just downgrade python
Check out this link which provides a great guide to downgrade python https://www.delftstack.com/howto/python/downgrade
Another option is to downgrade your numpy version using this command

Where v.v.v is the desired version, preferably the previous version.
You can also use conda to downgrade numpy, just like this

v.v.v is still the desired version, this is all for this method. If this does not work, please try the method bellow.
Solution 2 : install numpy 1.19.5 and take care of compatibility issues
The error will also happen if you use numpy version >1.19.5 with tensorflow 2.5
If you have tensorflow 2.5 you can only work with numpy version 1.19.5 and python 3.9
You can install numpy 1.19.5 like this
