QUESTION
I am estimating a model using the pyMC3 library in python. In my "real" model, there are four parameter arrays, two of which have over 170,000 parameters in them. Summarising this array of parameters is too computationally intensive on my computer. I have been trying to figure out if the summary function in arviz will allow me to only summarise one (or a small number) of parameters in the array. Below is a reprex where the same problem is present, though the model is a lot simpler. In the linear regression model below, the parameter array b has three parameters in it b[0], b[1], b[2]. I would like to know how to get the summary for just b[0] and b[1] or alternatively for just a single parameter, e.g., b[0].
ANSWER
Answered 2021-May-28 at 15:34To use coords for this, you need to update to the development (which will still show 0.11.2 but has the code from github or any >0.11.2 release) version of ArviZ. Until 0.11.2, the coords argument in summary was not used to subset the data (like it did in all plotting functions) but instead it was only taken into account if the input was not already InferenceData in which case it was passed to the converter.
With older versions, you need to use xarray to subset the data before passing it to summary. Therefore you need to explicitly convert the trace to inferencedata beforehand. In the example above it would look like:
QUESTION
I know this is probably a basic question, but I'm just getting into GUI building and haven't needed to dabble much in classes for that matter. I have some code (see below) to handle the GUI portion of the program (the CLI version is already running perfectly, but management runs for the hills whenever they see a CLI...), but I can't quite get it to work out. FYI running python 3.9.1 and wxPython 4.1.1 Phoenix (though wx.version also spits out wxWidgets 3.1.5, if that's relevant) on Windows 10
A lot of the code was based around examples / other folks asking stuff here, and unfortunately I can't find the original posts to credit them, but this is really just for learning and once I have a grasp of what I'm doing I'll be writing everything from scratch. So to the original authors, I apologize, but I thank you enormously!
The program is to display a "start" screen (frame), with just a title and single button. On clicking the button, a modal file dialog box opens where the user selects the .csv data file to use, the start frame disappears, and a new frame appears with a view of the data in the right pane (in a grid sizer) and some drop downs and radio buttons in the left pane. The last drop-down (self.inputNum) will be bound to an event handler which will add a number of additional drop-downs for the user to select the different targets to analyze (the number of course being determined by their selection in the self.inputNum combobox). However, when running the script, I get an error
ANSWER
Answered 2021-Apr-28 at 17:12Sorry folks, my pre-coffee brain was calling CreateGrid() when the function is defined as createGrid(). There were a few other mistakes in the code (event handlers that referred to buttons that I no longer had implemented, calling StartFrame.makeMenuBar from a different class without also importing the functions StartFrame.makeMenuBar called, etc).
But still feel free to point out inefficiencies and redundancies and other various un-pythonic things I'm doing. Still learning :)
QUESTION
So, I don't dabble in Javascript much, but I'm attempting to format a string from something like '2021-05-24 05:23 PM' to something like 2021-05-24 17:23. Is theres a library I could use or a built in method I haven't user properly yet? Thanks!
...ANSWER
Answered 2021-May-26 at 17:01You can use this function. It will receive a datetime string of 12 hours format as parameter and return the 24 hours format time.
QUESTION
I've been wanting to incorporate systray functionality into my Flutter app so I went to modify the native C++ code that initiates the window etc to see if I could hook into it.
Despite not having much prior experience in C++ I have been able to create an icon for my app in the systray with a menu that allows the window to be shown again when hidden (using ShowWindow(hwnd, SW_HIDE);) and to quit entirely.
However when an option in my systray menu is selected to show the window again using ShowWindow(hwnd, SW_NORMAL); after being hidden, the app stays blank like this:
Then, when the window is finally interacted with, the contents of the window show again:
Here is the code that I have added so far to my win32_window.cpp (from a default Flutter application). I haven't included the entire functions because I thought it would make things less clear, but I will also attach the full win32_window.cpp at the end of this post. Win32Window::CreateAndShow():

Answered 2021-May-20 at 20:29Ok so I've worked out why it wasn't working. When closing the window, I couldn't just use SW_HIDE, but SW_MINIMIZE too. Otherwise attempting to redraw the window wouldn't work correctly:
QUESTION
I am using the following code to create and excel file using xlsxwriter and openpyxl to edit it as I may need to read from other excel files later down the line, however when I try to open the file it gives me an error that the excel file is corrupt or the extension is incorrect. When the source file is saved as .xlsm this error is not present, I would like to know why that is.
...ANSWER
Answered 2021-May-19 at 10:15The issue is that you are setting keep_vba=True but the file you are dealing with isn't a xlsm file and doesn't have a vbaProject file. Just set it to false or omit the option.

QUESTION
I see a lot of info regarding serializing tables on kdb but is there a suggested best practice on getting functions to persist on a kdb server? At present, I and loading a number of .q files in my startup q.q on my local and have duplicated those .q files on the server for when it reboots.
As I edit, add and change functions, I am doing so on my local dev machine in a number of .q files all referencing the same context. I then push them one-by-one sending them to the server using code similar to below which works great for now but I am pushing the functions to the server and then manually copying each .q file and then manually editing the q.q file on the server.
...ANSWER
Answered 2021-Apr-01 at 18:19In my opinion (and experience) all q functions should be in scripts that the (production) kdb instance can load directly using either \l /path/to/script.q or system"l /path/to/script.q", either from local disk or from some shared mount. All scripts/functions should ideally be loaded on startup of that instance. Functions should never have to be defined on the fly, or defined over IPC, or written serialised and loaded back in, in a production instance.
Who runs this kdb instance you're interacting with? Who is the admin? You should reach out to the admins of the instance to have them set up a mechanism for having your scripts loaded into the instance on startup.
An alternative, if you really can't have your function defined server side, is to define your functions in your local instance on startup and then you send the function calls over IPC, e.g.

QUESTION
To preface, I'm currently still learning Swift and just wanted to have a dabble at trying to send data to some kind of backend from within my app. Not sure if important but if so:
- I am using fast comet as a web server with a PHPMyAdmin database in SQL. (struggling to get my head around it so that may be said incorrectly, apologies in advance!)
From what I can gather (please say if I've got this backwards), the executions on the database are written in SQL which I have included in my fetch request for my app (working successfully). The PHP file acts as a bridge to open a connection between the database and my end.
I've tried (semi-successfully) for 3 days to write a POST request in swift that will send the data from my app and insert it into my database. When I say semi-successfully, I mean that when triggering the inert method in my swift code from the app, data DOES get inserted into the database but it is the data on the alternative side of the nil-coalescing operator and not my data. This leads me to believe that all is (just about) okay with my .PHP file and that there is either a problem with my swift code, or that I've not set something up correctly within the database itself?
database with table named "Students" - consists of 5 fields:
id: INTfirst_name: TEXTlast_name: TEXTsubject: TEXTgrade: INT
swift - what I'm trying to insert into the database:
id: IntfirstName: StringlastName: Stringsubject: Stringgrade: Int

...ANSWER
Answered 2021-Feb-11 at 18:31Usually, the Maven POM is both build POM and consumer POM. This is not ideal, and will probably change in future versions of Maven.
At the moment, your best option seems to be the flatten Maven plugin, which allows you to remove "unnecessary" parts of the POM before uploading it.
