QComboBox does not have a placeholder text option but you can achieve this by doing

Ok, here is one way to obtain what you want in about 2min. Some tickers are bad, that's why it crashes.

Here's the code. I use joblib for threading or multiprocess since it doesn't work in my env. But, that's the spirit.

For a more clear output of the Round Keys with hexadecimal values replace print_matrix e.g. by:

I posted the same issue on Alembic's GitHub repo, and was pointed to the right direction there. Link to the issue.

Pasting the solution below as well:

Found it! I decided I'm diving deeper. So what I did is to comment-out every table that had a foreign key in it and ran migrate - worked. Then I started adding one table at a time from the ones that did have a foreign key and voila! I found that one of the tables had a db.foreignKey('tableName') (without specifying the actual column on which the constraint should apply 🤦 ). So no bug here, but I guess a more descriptive error would've saved me a good bit of time spent over this, lol. To verify- after fixing the misconfiguration, I cleaned up the migrations folder and restarted my PostgreSQL container (which started a brand new db from scratch) and ran the migrate command to create a single revision which includes all models at once- and it works! 🎉

I don't see what arrays have to do with your question. Presumably, you want to insert multiple rows. That would be:

Please try something like this. Note the use of pg_query_params() instead of pg_query() for the insert to guard against SQL injection.

Check the encoding your files (Status Bar) and the project (Settings | Editor | File Encodings) have.

Try adding -Dfile.encoding=UTF-8 into Help | Edit Custom VM Options file and restart IDE.

Also check that the console has Font set (Settings (Preferences on macOS) | Editor | Color Scheme | Console Font) which is capable to display all the glyphs.

The code that you have posted is a pretty good example of filtered backprojection (FBP) and I believe could be useful to people who wanted to learn the basis of FBP. One can use the function iradon(...) in MATLAB (see here) to perform FBP using a variety of filters. In your case of course, the point is to learn the basis of the central slice theorem and so finding a short cut is not the point. I have also learned a lot and refreshed my knowledge through answering to your question!

Now your code has been perfectly commented and describes the steps that need to be taken. There are a couple of subtle [programming] issues that need to be fixed so that the code works just fine.

First, your image representation in Fourier domain may end up having a missing array due to floor(diagDim/2) depending on the size of the sinogram. I would change this to round(diagDim/2) to have complete dataset in fimg. Be aware that this may lead to an error for certain sinogram sizes if not handled correctly. I would encourage you to visualize fimg to understand what that missing array is and why it matters.

Second issue is that your sinogram needs to be transposed to be consistent with your algorithm. Hence an addition of sino = sino'. Again, I do encourage you to try the code without this to see what happens! Note that zero padding must be happened along the views to avoid artifacts due to aliasing. I will demonstrate an example for this in this answer.

Third and most importantly, imContrib is a temporary holder for an array along fimg. Therefore, it must maintain the same size as fimg, so

I have used:
