QUESTION

How to create a progress bar for iterations happening within installed modules

Asked 2022-Jan-01 at 21:07

I am aiming to create a progress bar for an iteration happening inside an installed module.

To create a progress bar for an iteration inside a user-defined function, I pass an tqdm.notebook.tqdm_notebook object as iterable:

Of course generally there is no way to directly modify some existing code you didn't write yourself (whether or not it's "installed" is not the issue).

If you think it's really of general use or interest you could propose a patch to allow this function to take, e.g., a callback function to call on each loop. It might be useful if it's a slow function in general (I did notice some things in the implementation that could be changed to speed it up, but that's another matter).

You could of course find a number of clever hacks to make it work in this one specific case, though it would be fragile considering that it's a hack designed specifically to the implementation details of this function. I found a few possibilities for this.

The simplest seems to be this stupid trick:

Make an ndarray subclass (I called it tqdm_array) which when iterated in Python returns an iterator over a tqdm progress bar which wraps the array itself:

How to save a QTable to a file (.txt, .csv, etc.)

Asked 2021-Apr-19 at 09:47

I am trying to save a QTable object which originates from a Isophote list of an elliptical isophote fit, to really any filetype (.txt, .csv, etc.) that allows me to simply just load it back into the script without having to clean it or any of that sorts.

The QTable is created as follows:

Astropy already has numerous built-in formats for saving Tables with Table.write.

For QTable in particular, if you want a round-trippable text-based format the ECSV format is highly recommended, as it also outputs metadata concerning each column's types and units. If you name your file with a .ecsv extension, this format is used automatically. For example:

QUESTION

Problem with correctly placing results in specific list in python

Asked 2021-Mar-23 at 16:48

I am currently trying to run a set of images (masked arrays / masked 'fits' files) of m87 through an isophote fitting function. Hereby one reference fit has been performed earlier in the script, which provides the function with the isophotes geometry, that are then used to sample the remaining images of the galaxy. The function looks as follows:

The below looks wrong to me - should you not be appending "iso_" to isolist_temp within the for loop?
