kandi X-RAY | lambda Summary

lambda is a JavaScript library typically used in Serverless, Function As A Service applications. lambda has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

Here is a vanilla AWS Lambda example for performing a sum. Given event.query.x = 1 it will return {count:2}. A huge amount of vanilla AWS Lambda code is working around quirky parameter validation. API Gateway gives you control over the parameters you can expect but this still means one or more of: headers, querystring, form body, or url parameters. Event source style lambdas are not much better because you can often still get differing payloads from different origin sources. In the example above we are validating one querystring parameter x. Imagine a big payload! . Worse still, writing a good program we want to use JavaScript's builtin Error but it still needs manual serialization (and you still lose the stack trace). The latter part of this vanilla code uses the funky AWS context object.

The n2 - n1 in the case of a negative number as a result when converted to bool will yield true. So n1 turns out to be less than n2. That's why it is a bad practice to use ints in such Boolean context.

Yes, as stated in the documentation:

...comparison function object which returns true if the first argument is less than the second

But the implementation of the comparison here leads to failure. Try this and see for yourself:

Columns not properly moving in QTableView (QAbstractTableModel) using beginMoveColumns?

Asked 2021-Jun-15 at 20:13

I am trying to use beginMoveColumns to move a single column over in a QTableView, but it doesn't work properly in my example below. The cell selections get shuffled and column widths don't move. Moving rows using the same logic seems to work correctly. What am I doing wrong?

Turns out it was a bug, I made a bug report here: https://bugreports.qt.io/browse/QTBUG-94503

As a workaround I just clear cell selection on column move, and use this snippet to move column widths

I have translated a program from javascript to python 3.9 and I am only missing sorting the result, but I just can't get any further.

The list consists of dicts that has an id "components", which is itself a list.

QUESTION

QtTest under PyQt5 fails when widgets-under-test have to be visible to work

Asked 2021-Jun-15 at 17:01

I've started to create UI tests for my PyQt5 widgets using QtTest but have run into the following difficulties:

In order to speed up things, some of my widgets only perform operations when visible. As it seems that QtTest runs with invisible widgets, the corresponding tests fail.
For the same reason, I cannot test program logic that makes a subwidget visible under certain conditions.

Is there a way to make widgets visible during test? Is this good practice (e.g. w.r.t. CI test on GitHub) and is QtTest the way to go?

I have tried to use pytest with pytest-qt without success as I couldn't find a proper introduction or tutorial and I do know "Test PyQt GUIs with QTest and unittest".

ANSWER

Answered 2021-Jun-15 at 17:01

The problem is simple: QWidgets are hidden by default so isVisible() will return false, the solution is to invoke the show() method in init() to make it visible:

You need to define a different surrogate posterior. In Tensorflow's Bayesian linear regression example https://colab.research.google.com/github/tensorflow/probability/blob/master/tensorflow_probability/examples/jupyter_notebooks/Probabilistic_Layers_Regression.ipynb#scrollTo=VwzbWw3_CQ2z

you have the posterior mean field as such
