QUESTION
I want to make a program that randomly simulates the flow of a champions league tournament (football/soccer tournament). The format of the tournament is as follows:
- There are 32 teams that qualify each year.
- The teams are then randomly distributed into 8 groups containing 4 teams each.
- The teams all play each other and 2 of the best performing ones qualify to the next round (round of sixteen)
- The matchups are decided by randomly selecting the teams 2 at a time with the constraint that no two teams from the same group may face each other again
- The winner then progresses to the next stage and so on and so forth until we have a winner.
In my program I have tried to implement this format using the random module in python. However, once every 4-5 iterations I get an index error at either the round of 16 selection step or the quarter final selection step. I cant seem to understand why. Please help

I need to check if the numbers in $qt1, $qt2 and $qt3 are negative and if any of them are negative not run the rest of the code, if they are 0 or positive then run the rest of the code. I need to write more stuff so I can post the question so sorry if I am making you read this for nothing, but I just need what I had asked for, I searched online and couldn´t find anything to help me. My level of codding is really basic so please try and not make something super complex. And thank you for anyone how is willing to help.

I am trying to utilize Querydsl to fetch some results from a table. So far, this is what I have tried -
Assume there are 5 entities named T1..T5. And I am trying to do this SQL query in Querydsl -
...ANSWER
Answered 2020-Aug-05 at 14:27The complexity is not in the predicate or in QueryDSL, but in the fact that you're executing it in a subquery that has to be executed for every row in the result. Depending on the total result set size, this may become increasingly difficult to compute. It is however equally complex among QueryDSL, Hibernates HQL, JPA's JPQL or your databases SQL. So the SQL you're trying to generate, will be just as slow.
You might succeed at optimising the query using a limit clause. Adding a limit clause to query in QueryDSL is quite trivial: .limit(1)
. So then your query becomes:
QUESTION
I am having nn Actor Critic TD3 model with LSTM in my AI. For every training, I am creating batches of sequential data and training my AI.
Can someone expert please help to let know if I require epochs as well for this AI.And in general how many epochs can I run with this code, because I am creating many batches on one training step is it feasible to have epochs as well.
Below is training step code
...ANSWER
Answered 2020-Aug-01 at 09:38First I will say this, generally reinforcement learning requires A LOT of training. This is however heavily dependent on the complexity of the problem you are trying to solve. The situation may be made worse if your model is complicated (e.g. when using a LSTM). When training an agent to play Atari games you can expect needing up to 1 million episodes (depending on the game and the approach used).
With regard to epochs, if you mean repeated use of a particular episode (or collection of episodes) for training then it will depend on whether your using an on or off policy approach (for off policy this is like experience replay, epochs is the wrong word). Actor-Critic methods are generally on policy, which means they require fresh data at each stage of training. Once an episode has been used for training it should not be used again. For more information about the difference between on/off policy I recommend taking a look at Sutton's book.
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)

I have created a custom environment in open ai gym and i am facing error while loading the weights Could some one help me to resolve the issue . I am training a TD3 network in a custom environment and i have trained successfully but while inferencing i am facing this issue

The weights you saved were not from the model you are using here. Make sure to load the correct checkpoint, which was created when training this particular model.
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 have a text area of words. There is a jQuery function that will loop over an array to search for each work within the text, if it find it puts it in an array, then displays it. This works well. The text area is editable allowing a user to modify the text and then search again (Allowing for correcting spelling or context). After modifying the text and doing the function again it only finds a substring of the string, not the full thing, see below:
Text to search: I live on the Q53 Route. I want to see the Q3 route near my house.
If you added Q44 at the end after the period it will only find Q4..
...ANSWER
Answered 2020-Mar-18 at 17:57For this to work as you expect you need to ensure a full match on the Qxx
value, not a partial match. To do that you can use a regular expression utilising word boundaries:

Install qt2
You can use qt2 like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
