Can you perform loops or iterate (over devices and languages) within the fastlane fastfile or lanes?
I need to do something before and after each the simulator launches / ends.
Yes, you can use any Ruby command in a fastlane lane.
So for example:
lane :print_images do
images = Dir[File.dirname(some_search_path) + '/*.png']
images.each do |image|
UI.message("found image at: #{image}")
end
end

I am trying really hard to start with a simple skeleton on Roblox Studio, and then change one of the checkpoints (or all of them) so that they flash.
I thought to do that by using a script that I saw online that changes the transparency from 1 to 0 and back every 1 second.
So I tried this (I added this to all Checkpoints quite consistently in the same way):
and this (for this one I just added the part at the bottom):
but whenever I played in the Studio to test it I always got static checkpoints:
It is either the script is not running, or transparency is not the right way to go or what?
The "Checkpoints" folder has many objects in it that are called "Checkpoint". If you want to flash a particular one from its child script, you could do this instead:
while (true) do
script.Parent.Transparency = 1
wait(1)
script.Parent.Transparency = 0
wait(1)
end
it will only flash its parent (the Checkpoint).
I've been given a task to set up an openai toy gym which can only be solved by an agent with memory. I've been given an example with two doors, and at time t = 0 I'm shown either 1 or -1. At t = 1 I can move to correct door and open it.
Does anyone know how I would go about starting out? I want to show that a2c or ppo can solve this using an lstm policy. How do I go about setting up environment, etc?
To create a new environment in gym format, it should have the 5 functions mentioned in the gym.core file.
https://github.com/openai/gym/blob/e689f93a425d97489e590bba0a7d4518de0dcc03/gym/core.py#L11-L35
To lay this down in steps-
Define observation space and action space for your environment, preferably using gym.spaces module.
Write down the step function which performs agent's action and returns a 4 tuple containing - next set of observations from the environment , reward ,
done - a boolean indicating whether the episode is over , and some extra info if you want.
Write a reset function for the environment to reinitialise the episode to a random start state and return a 4 tuple similar to step.
These functions are enough to be able to run an RL agent on your environment.
You can skip the render, seed and close functions if you want.
For the task you have defined,you can model the observation and action space using Discrete(2). 0 for first door and 1 for second door.
Reset would return in it's observation which door has the reward.
Then agent would choose either of the door - 0 or 1.
Then perform a environment step by calling step(action), which will return agent's reward and done flag as true - signifying that the episode is over.
Frankly, the problem you describe seems too simple to accomplish for any reinforcement learning algorithm, but I assume you have provided that as an example.
Remembering for longer horizons is usually harder.
You can read their documentation and toy environments to understand how to create one.
I have created task on controller and there is loop which is loading for 100 times.
Now I want to load it for 25 times and pause that loop for 1 min and after that it will execute next 25 items same for next 25.
I have checked it with sleep but its not working.
Can you please advise me if is there any way on plugin event or any other method.
Thanks
This is actually unrelated to Joomla! Since you're creating a long running process you need to start it with something else than a browser. A CRON job is a good idea here if you want to execute this operation multiple times. Otherwise it can run via command line. Make sure the max_execution time setting of PHP does not cause any trouble.
If you still need this within Joomla please have a look at the CLI documentation.

I am looking for a way to save 'everything' in the matlab session when it is stopped for debugging.
Example
function funmain
a=1;
if a>1
funsub(1)
end
funsub(2)
end
function funsub(c)
b = c + 1;
funsubsub(c)
end
function funsubsub(c)
c = c + 2; %Line with breakpoint
end
When I finally reach the line with the breakpoint, I can easily navigate all workspaces and see where all function calls are made.
The question
How can I preserve this situation?
When debugging nested programs that take a long time to run, I often find myself waiting for a long time to reach a breakpoint. And sometimes I just have to close matlab, or want to try some stuff and later return to this point, so therefore finding a way to store this state would be quite desirable. I work in Windows Server 2008, but would prefer a platform independant solution that does not require installation of any software.
What have I tried
1. Saving all variables in the workspace: This works sometimes, but often I will also need to navigate other workspaces
2. Saving all variables in the calling workspace: This is already better as I can run the lowest function again, but may still be insufficient. Doing this for all nested workspaces is not very convenient, and navigating the saved workspaces may be even worse.
Besides the mentioned inconveniences, this also doesn't allow me to see the exact route via which the breakpoint is reached. Therefore I hope there is a better solution!
Code structure example
The code looks a bit like this
function fmain
fsub1()
fsub2()
fsub3()
end
function fsub1
fsubsub11
fsubsub12
...
fsubsub19
end
function fsub2
fsubsub21
fsubsub22
...
fsubsub29
end
function fsub3
fsubsub31
fsubsub32
...
fsubsub39
end
function fsubsub29
fsubsubsub291
fsubsubsub292% The break may occur in here
...
fsubsubsub299
The break can of course occur anywhere, and normally I would be able to navigate the workspace and all those above it.
Checkpointing
What you're looking to implement is known as checkpointing code. This can be very useful on pieces of code that run for a very long time. Let's take a very simple example:
f=zeros(1e6,1);
for i=1:1e6
f(i) = g(i) + i*2+5; % //do some stuff with f, not important for this example
end
This would obviously take a while on most machines so it would be a pain if it ran half way, and then you had to restart. So let's add a checkpoint!
f=zeros(1e6,1);
i=1; % //start at 1
% //unless there is a previous checkpoint, in which case skip all those iterations
if exist('checkpoint.mat')==2
load('checkpoint.mat'); % //this will load f and i
end
while i<1e6+1
f(i) = g(i) + i*2+5;
i=i+1;
if mod(i,1000)==0 % //let's save our state every 1000 iterations
save('checkpoint.mat','f','i');
end
end
delete('checkpoint.mat') % //make sure to remove it when we're done!
This allows you to quit your code midway through processing without losing all of that computation time. Deciding when and how often to checkpoint is the balance between performance and lost time!
Sample Code Implementation
Your Sample code would need to be updated as follows:
function fmain
sub1done=false; % //These really wouldn't be necessary if each function returns
sub2done=false; % //something, you could just check if the return exists
sub3done=false;
if exist('checkpoint_main.mat')==2, load('checkpoint_main.mat');end
if ~sub1done
fprintf('Entering fsub1\n');
fsub1()
fprintf('Finished with fsub1\n');
sub1done=true;
save('checkpoint_main.mat');
end
if ~sub2done
fprintf('Entering fsub2\n');
fsub2()
fprintf('Finished with fsub2\n');
sub2done=true;
save('checkpoint_main.mat');
end
if ~sub3done
fprintf('Entering fsub3\n');
fsub3()
fprintf('Finished with fsub3\n');
sub3done=true;
save('checkpoint_main.mat');
end
delete('checkpoint_main.mat');
end
function fsub2
subsub21_done=false;subsub22_done=false;...subsub29_done=false;
if exist('checkpoint_fsub2')==2, load('checkpoint_fsub2');end
if ~subsub21_done
fprintf('\tEntering fsubsub21\n');
fsubsub21
fprintf('\tFinished with fsubsub21\n');
subsub21_done=true;
save('checkpoint_fsub2.mat');
end
...
if ~subsub29_done
fprintf('\tEntering fsubsub29\n');
fsubsub29
fprintf('\tFinished with fsubsub29\n');
subsub29_done=true;
save('checkpoint_fsub2.mat');
end
delete('checkpoint_fsub2.mat');
end
function fsubsub29
subsubsub291_done=false;...subsubsub299_done=false;
if exist('checkpoint_fsubsub29.mat')==2,load('checkpoint_fsubsub29.mat');end
if ~subsubsub291_done
fprintf('\t\tEntering fsubsubsub291\n');
fsubsubsub291
fprintf('\t\tFinished with fsubsubsub291\n');
subsubsub291_done=true;
save('checkpoint_fsubsub29.mat');
end
if ~subsubsub292_done
fprintf('\t\tEntering fsubsubsub292\n');
fsubsubsub292% The break may occur in here
fprintf('\t\tFinished with fsubsubsub292\n')
subsubsub292_done=true;
save(checkpoint_fsubsub29.mat');
end
delete('checkpoint_fsubsub29.mat');
end
So in this structure if you restarted the program after it was killed it would resume back to the last saved checkpoint. So for example if the program died in subsubsub291, the program would skip fsub1 altogether, just loading the result. And then it would skip subsub21 all the way down to subsub29 where it would enter subsub29. Then it would skip subsubsub291 and enter 292 where it left off, having loaded all of the variables in that workspace and in previous workspaces. So if you backed out of 292 into 29 you would have the same workspace as if the code just ran. Note that this will also print a nice tree structure as it enters and exits functions to help debug execution order.

After a bit of googling, I found that using putvar (custom function from here: http://au.mathworks.com/matlabcentral/fileexchange/27106-putvar--uigetvar ) solved this.
I have a loop that has a command I want to execute at a specific time, say 3 seconds from now. But I don't want to add a delay because I want my rest of the statements and the loop to execute continuously without delay. Is there any way I can store statements in a buffer to execute at a required time?
You need to set up a timer object. The "Display message using Timer"-Example shows exactly what you need.
Have you tried tic and toc? Like this:
tic
executeFlag = 1;
while(1) % Your loop here.
if (toc > 3) && (executeFlag)
timedThing(); % The thing to run on a timer.
executeFlag = 0;
end
everythingElse(); % Everything else you need to do.
end
It's not pretty, but it will do the job. You can remove the executeFlag if you want the timed thing to run after a certain time.
Let me know if this doesn't do it for you, and I'll take another shot at it.
