QUESTION
I'm populating datagridview with random numbers from a given range, but when I generate a big amount of numbers - my program hangs while generating them. That could last more that a minute (depending on the amount). I know that I can show a progress using ProgressBar. I've tried to use it, but I haven't got anythin. Any examples of using it?
Here is my code:
...ANSWER
Answered 2021-May-08 at 22:07Your program "hangs" while adding data to the UI because you are doing all the work in the UI thread effectively blocking the thread until your loop is done. So you need to handle this heavy duty work in a seperate thread. But you can only change the UI from the UI/main thread so something like this would throw an exception:

Pls find a way to fix it :/ I'm not really good at scripting stuff.
There is another script: Server script. But i don't think it's the cause of this problem.
I will post it anyways
Btw it's for a shooter game that I'm making (just to add some workds soo i can post it)
When it breaks it send's out this:

I'm new in android. I've implemented code to play random sounds when clicking an ImageButton, first problem is that it does not play random sounds all the time when button is clicked - it choose one sound and plays only this one, when I press the button next time it plays same sound as the first time when button is clicked - I would make this random every time when button is clicked. Also when I added function which counts how many times this button is clicked, app stopped to play sounds anymore, it only shows how many times my button was clicked, but there is no more audio. Here is my code:

QUESTION
I am trying to do batch processing with nn.lstm
From the documentation https://pytorch.org/docs/master/generated/torch.nn.LSTM.html I get that h0 and c0 should be of dimension:(num_layers * num_directions, batch, hidden_size).
But when I am trying to give input tensor with batch size>1 and h0 , c0 batch size>1. It is giving me error stating: "RuntimeError: Expected hidden[0] size (1, 1, 256), got (1, 611, 256)"
Here is my code: it contains 1 memory buffer, Actor, Critic, TD3, ENV classes and main training is in TD3 which has actor and critic objects.
Can someone please help a check what am i missing here.
...ANSWER
Answered 2020-Jul-26 at 08:54Did you make the input dimensions as required in nn.LSTM as well? I saw that you haven't set batch_first = True, and hence the input tensor has to be in the form
- (seq_len, batch, input_size)
QUESTION
I am trying to train a Actor Critic Model with LSTM in both actor and critic.
I am new to all this and can not understand why "RuntimeError: Dimension out of range (expected to be in range of [-1, 0], but got 1)"
is comming.
I am forwardPropagating from actor and getting error
below is my code and error message.I am using pytorch version 0.4.1
Can someone please help to check what is wrong with this code.
...ANSWER
Answered 2020-Jul-24 at 12:59Got it.
The input of the lstm layer has different shape. https://pytorch.org/docs/master/generated/torch.nn.LSTMCell.html
QUESTION
I am trying to add an lstm layer to my previous working AI model. On adding the model I am getting this error when training the batch to my AI.
earlier without the LSTM the error was not there and it worked fine.
Input batch size 100 doesn't match hidden[0] batch size 1.
I am using nn.LSTMCell
can anyone please help a check if I am missing some parameter to init my lstmcell so it can take batch inputs as well.
below is my code...
...ANSWER
Answered 2020-Jul-24 at 08:16If you initialize your cell state and hidden state with zeros, there is no need to provide initialization at all, it will be provided for you (as a default, please see docs). However, should you decide to do it on your own, you should always take into account batch size (which might be different every iteration).
In the end, both cell and hidden state for nn.LSTMCell
have shape (batch_size, hidden_size)
whereas you initialize those once in the constructor with shape (1, hidden_size)
. You have to move initialization to forward()
and with each call get batch size from x
which should be just x.shape[0]
As a side note, you are using nn.LSTMCell
which is just a single cell computation. Used once does not really make sense, make sure that's what works for you. Maybe just nn.LSTM
instead?
QUESTION
I came across this leetcode problem Insert Delete GetRandom where it is asked to implement a Data Structure to support Insert, Delete and getRandom in average O(1) time, and solved it as using map and a vector. My solution passes all the test cases except for the last one and I'm not able to figure out why? The last test case is really very large to debug.
I changed my code a little bit and then it passes but still didn't got why the previous one didn't pass.

QUESTION
I need help for my project. I have an array that look like this?
...ANSWER
Answered 2020-Jun-04 at 13:16You can use .append
to add an array to the end of another array. The problem here is that numpy.append
flattens the array first, ie. numpy.append([1 0], [0 1])
is [1 0 0 1]
. See the numpy docs on .append
.
QUESTION
I am trying to use numpy in Python in solving my project.
I have a random binary array
rndm = [1, 0, 1, 1]
and a resource_arr = [[2, 3], 4, 2, [1, 2]]
. What I am trying to do is to multiply the array element wise, then get their sum. As an expected output for the sample above,
output = 5 0 2 3
. I find hard to solve such problem because of the nested array/list
.
So far my code looks like this:

QUESTION
So I'm designing a game in which you have to choose the larger number between two numbers in order to win the prize. There are five buttons (each has a random number given in it) and a button to reset
For the first time, Button4 (The 2nd from right)and Button 5(the right one) The number in Button5 will be shown and the number in Button4 will be hidden Like this: 1st round
If you guess it right, you will win the number you guess right
If you guess it wrong, the game is over and you will only win the amount number you guessed right in the previous round
For example (1st round: Button4 & Button5(8) +++ You choose Button5(8), it's correct, now you win 48 dollars 1st round
2nd round: Button3 & Button4(Shown, it turns out that it's 4) +++ You choose Button4 The game is over because the number in Button3 is 7, which is larger than 4 You only win 48 dollars (from the previous round) Like this: 2nd round
Note: Button1-Button3 are disabled before the program starts
QUESTION
What I wanna ask is: After the game is over, how do you make the button3 & button4 not be able to click again?? So, the only way to play the game is to click the button reset I know there's a method like this:
...ANSWER
Answered 2020-May-20 at 11:07A work-around could be to check if the game is over when you click any of the buttons. So, handle the event, but in case the condition for the game over is True, just return and do nothing.
Use a global variable isGameOver
for this that saves the current status of the game (false
when it starts). You set it to true
when game is over and you show that message. That's what you can use to validate later if the action of the buttons should be done or not.
