NumPy module can be used to initialize the array and manipulate the data stored in it. The number.empty() function of the NumPy module creates an array of a specified size with the default value=” None”. Synta
Initialize 2D Array in Python Using thenumpy.full()Method This method will also initialize the list elements, but it is slower than the list Comprehension method. The complete example code is as follows: importnumpy dim_columns=2dim_rows=2output=numpy.full((dim_columns,dim_rows),0).tolist...

Now we need to initialize the first state. An action is two-dimensional tensor: [1, 0] represents “do nothing” [0, 1] represents “fly up” Theframe_stepmethod gives us next screen, reward, and information as to whether the next state is terminal. The reward is0.1for each bird’s...
