pong from pixle with CNN and policy gradient - python

i get a stuck at this point , i've readed "pong from pixel" of kapathy blog, and i wanna improve this by integrate CNN model then i've got this tutor from GG.
**link here:
https://github.com/yshvrdhn/Pong-Agent-Using-Policy-Gradients/blob/master/pong_keras.py
But i cannot run and dont know the usage of this line:
model= learning_model() ,plz someone can help me ???
***error that i got after compile these code :

It looks like you don't have theano installed. You can do so with:
pip install theano
As a side advice, I would also recommend virtual environments, so it will be easier to keep your projects isolated.

I would recommend working with Anaconda.

Tflite model m aker issue - undefined symbol table __scann_ops.os

It occurs when I attempt to use the tflite_model_maker library. Corrupted or outdated shared library file?
Okay, I discovered it could be fixed by simply installing scann using pip:
pip install scann

Numpy is Not a Generic Class

I am trying to learn Python and following along some modules. I am using Anaconda Powershell Prompt and using Python 3.7 from there. I am trying to follow along via the code below.
Everything works until I get to the line
from wrf import getvar
When I do that line I receive this

Looks like the last few lines return an error but as a beginner I have zero clue what this means.
This looks like a similar error to <class 'numpy.typing._dtype_like._SupportsDType'> is not a generic class when importing the plotly.express library - an incompatibility between wrf-python and numpy.
Try upgrading those libraries to the latest versions.

Error after updating scikit-learn to version 0.20.1 : cannot import name 'Empty' from 'queue'

I upgraded scikit-learn to version 0.20.1 using anaconda3 after getting an error message concerning balanced_accuracy_score from metrics in scikit-learn. This is apparently not available in version 0.19.
After this upgrade i get the following error:

Are you running this program from "C:\Users\Pieter\Python progs"?
Looks like you have a file named queue.py in "C:\Users\Pieter\Python pro
gs\" which is shadowing the actual module queue in multiprocessing lib. And hence the error.
There are two possible reasons for this:
Maybe this line:
from queue import Empty, Full
has been added in new version, so earlier it did not error even when your custom made queue.py was present.
Maybe you have created your queue.py recently after updating the scikit-learn and the above line was always present. In this case, error should occur on both versions.
Rename your program from queue.py and auto-compiled queue.pyc
to something else and it should work.

Module not found when using scipy

I have recently properly installed numpy and scipy. The following line runs without error.
import scipy
I am experiencing difficulty using scipy.io.wavefile. I have been trying to use the code from the "best answer" of this post.
However, when I try the first line,
from scipy.io import wavfile
I receive the following error and traceback,

ImportError: cannot import name 'ellipkm1' from 'scipy.special._ufuncs' (unknown location)
I do not understand why the module can not be found, if scipy is properly installed and can be imported by itself. I am using python 3.7.1. Could the code from the post be depreciated?
Apologies in advance for the long post.
Both error messages are complaining about the scipy.special._ufuncs module and a quick search revealed a few other posts, like this one, that suggest making sure you have the Visual C++ Redistributable Packages installed: https://www.microsoft.com/en-us/download/details.aspx?id=48145

IndentationError: expected an indented block
I executed this command in a terminal (ubuntu 16.04 LTS system). I did not find anything about this error and the indentation doesn't look wrong.
The SyntaxError is in your file new.py (I guess it's in your current working directory). Try to switch to a directory where no new.py file is present (or move the new.py file in another directory), then the internal scipy import should work without problems.
On the other hand you can just upgrade to scipy 0.19.x. They removed the import there and it should work without problems.
Note that it's always a bad idea to name python files like builtin-modules! That's a common source for exceptions or unexpected behaviour.
