QUESTION
I try to run this Neural Network script (for a regression model) There are two classes defined above. One is Standardizer class and other is Neural Net class. The Standardizer class normalizes all the values and the NeuralNet class builds the neural network that learns the data through feed forward and back propagation.
This function takes the the number of inputs, hidden units, and outputs as the three parameters.
The set_hunit function is used to either update or initiate the weights.It takes the weight as the parameter.
The Pack function packs the multiple weights of each layer into one vector. The unpack function does vice versa.
Forward pass in neural network propagates as shown below:
ππ=β(ππβ π)=ππβ π
Activation function is used to make the network non linear. We may use tanh or RBG or etc.
In the backward pass the function takes the the z values, Target values and the error as input. Based on the delta value, the weights and the bias are updated accoringly. This method returns the weight vector packed together of that particualr layer. Below are the functions that are excecuted during backward pass.
ππβπ+πΌβ1π1πΎππβ€((πβπ)πβ€β(1βπ2))βπ+πΌπ1π1πΎππβ€(πβπ)
The train function takes the feautures and the target as the input. The gradientf unpacks the weights,proceeds with the forward pass by calling forward function. Now error is calculated using results of forward pass. Now back propagation is proceeded by calling backward function with parameters as error, Z, T(Target), _lambda.
The optimtarget function tries to reduce the error by using the object function and updates the weights accordingly.
The use method is applied to the test data after training the model. Testing data is passed as parameter and it stadardizes the data. Then forward is applied on the data which returns the predictions
...This shows module not found error, but I have installed grad module with pip installation
ANSWER
Answered 2021-May-11 at 13:16Try to open command prompt and type pip install grad
or if you using jupyter notebook, make a new code shell and type !pip install grad
before you importing it
Hope that solves your problem

I have one sphere in my Pyqt5 window drawn by PyOpenGL:
Then, I am switching to the back buffer using self.swapBuffers() and then draw again to the back buffer but with a different color.
And with a mouse click, I am trying to read the back buffer color,
But it is giving me the value of the front buffer. The problem here, is it possible to read the value from the back, if so, what is exactly wrong here?

I've been trying to get a right click command working on the icontextbutton in maya using python. I know there is a popup menu, which is working fine, but i dont want a popup, as it adds a second click to the workflow, rather than having a command execute on RMB press. There seems to be no doc on the subject and google isnt helping either, so i am hoping anyone may have an idea, maybe some undocumented flags I'm unaware of. So LMB should execute one command and RMB should execute another. Is there any way of doing that ?
...ANSWER
Answered 2021-Jan-06 at 23:53I would recommend straight-up using Qt for this, instead of wrapping through Maya's Python stuff.
That said, you can achieve something mostly functional by hooking the RMB through an empty popupMenu

QUESTION
I have a script that detects mouse clicks. I need it to : [1. Move my cursor to a position 2. Click on that position 3. Move it back to the original position] and that will run whenever I click anywhere on the screen. The problem is, the click that script created is still registered and creates a loop back and forth. How can I change this behaviour, so it doesn't run the function when the click happens from the script, not from me?
...ANSWER
Answered 2020-Nov-26 at 09:23According to the document, you can use GetAsyncKeyState
:
The GetAsyncKeyState function works with mouse buttons. However, it checks on the state of the physical mouse buttons, not on the logical mouse buttons that the physical buttons are mapped to. For example, the call GetAsyncKeyState(VK_LBUTTON) always returns the state of the left physical mouse button, regardless of whether it is mapped to the left or right logical mouse button. You can determine the system's current mapping of physical mouse buttons to logical mouse buttons by calling GetSystemMetrics(SM_SWAPBUTTON).
Therefore, it will only be triggered when the mouse is changed in physical state, which can make the program work normally.
The reason for the two triggers is that the value of a
is set incorrectly. You only need to get the highest bit of the mouse state through the GetAsyncKeyState
function, as shown in the following code:
QUESTION
So i got this code which is working almost fine.. Its maybe a good starting point if u can help me.:
...ANSWER
Answered 2020-Nov-03 at 22:44Assuming:
- When you said "And if the LMB was released after 1 sec than i want to block the LMB for x time. So i coudnt hit it again", you meant that you wanted it so that the clicking the LMB wouldn't do any action during the block duration.
- You wanted it so that only if the second action was triggered (the one that sends a 'C' after a certain amount of time has passed), the block would be activated. This would allow you to repeatedly click the mouse to send A B, but you would have to wait for a second before you can send anything after A C.
Then the solution I came up with involves a toggled variable that determines whether the hotkey will do anything if the LMB is pressed. The toggle variable, switch
, is set to disable mode after the A C part of the script activates, but after one second (1000 milliseconds), the variable goes back to the "enabled" state. [For reference, when switch is 1, the hotkey is enabled, but if it is 0, it is disabled.]

QUESTION
I made a pause widget that I open when I hit the 'P' screen:
I will run you through what is happening in the blueprints:
- When the user presses the 'P' key
- Initiate the do once pre-defined functionality so that the user does not stack one pause screen over the other.
- Create the pause menu widget
- Add it to the viewport and make it a child of the play screen.
- When I load the widget into the viewport show the mouse cursor (which works). However, for some reason I need to press it once to activate the pause screen window. I do not know why?
- Then I am setting the pause game to true to tell that the game has been paused and freeze everything. After that, I am resetting the do once functionality because the player will only interact with the pause screen now.
Next, I made a pause screen widget blueprint in which I have a button called "Resume" and this is the "On-Clicked" event of that resume button:
In my resume game on clicked event blueprint:
- I am setting the paused game Boolean to false so that everything unfreezes.
- I am removing the current pause screen from the viewport.
- Then I am turning off the show cursor. When this happens, I still see the cursor but when I click in the window, then the cursor disappears. I want the cursor to disappear when I hit the resume button and not when I click in the window once. It's acting as if the window has lost focus. So, when I hit the LMB in the window it disappears.
What is happening? Is this behavior normal in UE4? If so, will the game behave as expected after production and if not, how do I solve this problem?
For more information I am following this tutorial on Youtube: < https://www.youtube.com/watch?v=hP_J5rMikhg&list=PLKMRiZuSgt-7wY7hfUzg8JcuTFXAf85jv&index=12 >
ANSWER
Answered 2020-Oct-21 at 19:21By default the game set the input to GameAndUI but when you have this or UIOnly (on a widget), it's not possible to hide the cursor, so to do properly set the input to UIOnly when you show your pause menu and set to GameOnly before removing the widget and normaly you don't have to hide the mouse, this will hide automaticaly here a example: Go Game, Go Pause
QUESTION
I'm trying to write a program which counts the number of mouse left and right buttons presses every 30 seconds since start in order to get statistics of mouse activity. But it doesn't count single rightclick, it counts rightclick as leftclick + rightclick combination. Also it doesn't output results after 30 seconds even if there was no clicks at all, instead it waits mouse button pressing after 30 seconds passed. I'm stumped. What should I change to fix this? Here is my code.
...ANSWER
Answered 2020-Oct-15 at 09:01Besides the elapsed time mentioned by Flimzy
You are running an infinite loop within an infinite loop, rightclickcounter() gets never executed. At least not in your timeframe.
Currently, you are starting lc counter -> wait 30 secs -> start rc counter -> wait 30 secs
