kandi X-RAY | mrl Summary
this is a modular rl code base for research. the intent is to enable surgical modifications by designing the base agent as a list of modules that all live inside the agent's global namespace (so they can all access each other directly by name). this means we can change the algorithm of a complex hierarchical, multi-goal, intrinsically motivated, etc. agent from ddpg to sac by simply changing the algorithm module (and adding the additional critic network). similarly, to add something like a forward model, intrinsic motivation, landmark generation, a new her strategy, etc., you only need to create/modify the relevant module(s). the agent has life-cycle hooks that the modules "hook" into. the important ones are: _setup (called after all modules are

QUESTION
I have a very basic question that is driving me crazy, and for the life of me I can't figure it out.
I have a workbook that has several sheets that contain cells that open up the same userform to be filled out. Currently, the code has closing the form return the workbook to one page in particular. I am trying to have the workbook return to the page that was previously being worked on; in doing so, I set up a public worksheet variable (wsWorking) that would be set to the sheet last clicked on before opening the UserForm. However, in doing so, I always get a "Run Time Error '9': Subscript out of range" message, and the debug message shows my wsWorking variable as empty.
If I put in the name of a sheet instead of trying to use the variable, I can open it to the page I want, but seeing as this page will be dynamic depending on what is being worked, that is not the desired outcome.
Declaration: '(in my ThisWorkbook module, (General) (Descriptions)
...ANSWER
Answered 2021-Apr-22 at 16:59ThisWorkbook is a class module with a PredeclaredId attribute that makes it accessible from anywhere, but its members are still its members. You can access any public member of ThisWorkbook from anywhere in your code, by qualifying it with the predeclared ThisWorkbook object:
QUESTION
I am currently working on a 2D-simulator game that takes place in a Perlin noise-generated terrain that is shown on a 41x23 grid. The player (as of the moment, at the center but not yet given an overlaying icon) can move using the arrow keys, but doing so will keep the player static but move the map accordingly. However, when I move, the JFrame lags like hell. Some JLabel instances change their ImageIcons slower than others, creating huge latency and un-"playability". I have tried replacing the inefficient function update with four functions that "efficiently" move the player faster - but the lag or delay remains. I have also reformatted and refactored the function, to no avail. So, I am stuck.
For more info, I am using 32x32 icons that represent the structures and the domain, and the JFrame is 1280x720 in size. I am confident that this is not due to hardware, as the program runs with other memory- or core- consuming programs. Is there any way to solve the lag or delay?
Main Class
...ANSWER
Answered 2021-Feb-02 at 15:55So far, Raildex's suggestion is working. The compilation of the map into a single buffered image has reduced the lag tremendously and made the game "playable". For additions in the code, I have made a texture class that supports the textures used; and a MapField whose object has fields that have the compiled BufferImage.

QUESTION
I have a datatable that is being populated with data from ajax->mysql database. After it is populated I use various datatables tools like "rowsGroup", "searchColumns" etc to make the table look better.
Is there any way I can then get the table body as a tbody element with td's and tr's and append it to a variable?
My problem is that I have the datatable looking as I want it when it is initialized in javsscript (with the filters and plugins etc applied) but I have no way of exporting it like that.
My question is, how can I export it to a variable looking exactly how it is so that I can save it somewhere and re-use it elsewhere on the page or project.
===TABLE INIT===
...ANSWER
Answered 2021-Mar-18 at 13:24For a more complex requirement like the one you have, you are going to need to combine DataTables capabilities with some extra logic (JavaScript, in this case) to iterate over the set of tables you need.
So, the following example is not a complete solution - it just shows how to create one copy of your original table, with an applied filter. But this could be extended to loop over each of your continents, one-by-one.
The code creates a variable called tableCopy which contains a clone of the original table. You can then use tableCopy.outerHTML to get the full HTML of the copied table.

I encounter a bug with libvlc where attempting to play video from YouTube result in error http stream error: local stream 1 error: Cancellation (0x8)
C++ code:
...ANSWER
Answered 2021-Mar-18 at 03:40Since Youtube URLs are not like other URLs for VLC, in the sense that you give a HTML URL to VLC, and that VLC needs to parse that HTML page and reconstruct the actual video URL (that's what the lua script does), you cannot give the HTML URL directly to the mediaplayer as a media.
Create a media from the HTML URL, as you have done.
QUESTION
My table looks like the following:
And basically I just want a row below the table indicating what the small red 1 and 2 means on their respective rows. I cannot find anything online to do with comments or footnotes in datatables. And I have tried to use the tfoot tag and append it to that but it looks awful (which I assume is datatables not agreeing with that method). Anyone know a solution for this?

QUESTION
I have video file which is only playable using proxy in vlc player, when I try to open it with vlcj I am unable to connect to this media - I've been trying to use http proxy configuration option in mrl ( http://path_to_media :http-proxy=proxy_address ) - but it didn't work for me yet. I've also tried setting environment variable http_proxy but it also didn't work for me. Could anyone tell me what I am doing wrong? Maybe there shouldn;t be a whitespace between path to media and configuration option? Maybe config options do not work on Windows? How can I access this video (I know I could use transcoding to do it but it seems like overkill, I feel there should be a simpler way)
ANSWER
Answered 2020-Nov-14 at 07:54You could make the request in Java, retrieve a stream and use https://github.com/caprica/vlcj/blob/de90d77bc288843b4d07dad84ff9d0515e906657/src/main/java/uk/co/caprica/vlcj/media/callback/AbstractCallbackMedia.java to give it to vlcj for playback.

QUESTION
I have around 180 xml files that are in a list xml_files. Now I need to iterate through those files, and combine them in 1 pandas dataframe. All xml files follow the same structure.
Can someone help me out with my code, I'm stuck at the point where I need to create 1 dataframe out of all the xml files. The doc variable contains the right structure that I need from the xml file.
ANSWER
Answered 2020-Jun-14 at 04:41One way to do that is to use pd.concat, as follows. Please note that some of the XML documents were invalid, and required preprocessing. Also, I had to distinguish between documents with a single row and documents with multiple rows.
