A: Why would the tokenizer for encoder-decoder model for machine translation use bos_token_id == eos_token_id? How does it know when a sequence ends? Not sure if this is really a coding question (maybe the ML or AI Tech proposals might be better suited). Not having distinct begin and end tokens is not that extraordinary. E.g. the GPT-2 tokenizer also uses only a single special token (rather than multiple distinct tokens). It is simply a des... (more) |

does that mean that you are trying to get some instance of jupyterhub running on a bare metal server (and you don't have contact details of the admin)?

A: make: How to compile all files in a directory. Each rule in the Makefile represents a single target. This means that your first makefile has a single target: `obj/library.o`. I guess that if there is only one target, `make` assumes that this is the target you want to build and does not require targets to be provided by the command line. As a resu... (more) |

A: How to mock methods like `pathlib.Path.is_dir`? It turns out that this is exactly what autospeccing is for.

How to mock methods like `pathlib.Path.is_dir`? I used to have some testing code for mocking a simple directory structure when working with `pathlib`. I recently tried to run these tests to learn that some of the internals in `pathlib` have changed in recent Python versions, breaking my mocking setup. I managed to resolve some of the issues alread... (more) |

This answer is missing one of the main reasons in the context of [OOP](https://en.wikipedia.org/wiki/Object-oriented_programming): indicating that a method (and therefore its class) is abstract. (more) |

Although Python is not necessarily an efficiency-oriented language, it might be useful to point out that this approach is probably not as efficient as a bisection algorithm. (more) |

Is adding a(n empty) `__init__.py` file in each subdirectory considered to be too much overhead? After all, this is the only thing necessary to make Python interpret a directory as a [Python package](https://docs.python.org/3/tutorial/modules.html#packages). (more) |

When to use custom iterators versus pointers I am working on a toy project where I have a container for which I would like to write an iterator that iterates over the values in the container. Because the values are stored in a (c-style) array, this would look something like this: ```c++ class MyClass { int data[10] {}; public: class M... (more) |

A: How to overwrite lines of STDOUT in Python? You can use the carriage return control character `"\r"` to return to the beginning of the line and overwrite text.

The problem is that it does not really make sense to write an answer about `BitSet` in this general context, since e.g. Python does not really have a data structure like that. This is probably also the reason why I assumed this was a Python and not a Java question.
My point is that by abstracting ... (more) |

Roughly speaking, tensorflow-graph is tensorflow-v1 and tensorflow-eager is tensorflow-v2. I don't think these tags would be that useful. Especially since there are generally not that much tensorflow questions thus far. (more) |

I definitely agree that showing non-working attempts is generally a good thing. I do feel that the non-working attempts should be conceivable from the standpoint of someone who could have this question, however. I just can't imagine that someone would think about tuples in this kind of scenario. (more) |

First of all, I hope it is clear that I did not intend to "attack" your question. I just found the topicality documentation a little ambiguous about this kind of question.
To me, software design/architecture/modelling is one level above the actual algorithm/data structure considerations. On a soft... (more) |

I have no problem with the language-agnostic tag. I think my main issue is that this question feels like it originated from Python and was then artificially generalised to cover all languages (or all languages with a data structure for sets that is implemented by a hashtable). In the end, this questi... (more) |

| Question | — |
Are questions about (abstract) algorithms and datastructures considered on-topic? I just noticed this question about data structures in the Q&A. Although algorithms and data structures are often (part of) a solution to a problem when writing software, this question is constructed in a way that aims to leave out the software part entirely. Especially, because I have a strong feel... (more) |

A: Should self-answered Q&A use separate answers for different techniques/approaches (even if there's a caveat that applies overall)? I believe one of the main strengths of Q&A websites is that they provide a more digestible alternative to dense documentation. Especially for programmers who do not yet know how to find/use the documentation for the language that they are working with. The answer (and even the question [^1]) is/ar... (more) |

I agree with @#53398 that this question comes over as too artificial. In the list you linked in the answer to the meta question, you list these top questions. One common aspect of these questions seems to be that they have very short and simple question statements. These questions are popular because... (more) |

A: Best practices to write functions for both execution modes in Tensorflow, eager and graph mode Tensorflow functions should typically work on both eager and graph tensors. This means that you can just use the following implementation: ```python def lintodb(x: float | tf.Tensor) -> tf.Tensor: """ convert signal to noise ratio (SNR) from linear to dB """ return 10. tf.math.log(x) / ...

A: Listen for key events in a CLI app First of all, the standard keystroke for interrupting a CLI program would be `ctrl + C` or whatever the windows equivalent is. Therefore, you will get the most consistent user experience if you use this standard keystroke for interrupting the program (rather than something custom like space). One... (more) |

tensorflow functions should work both on eager and graph tensors. I just tried `10. * tf.math.log(x) / tf.math.log(10.)` and it worked in both settings.
Similarly, you could use `tf.cast(x, dtype=tf.int64)` for the casting function (unless there is a specific reason why you would not want graph tens... (more) |

A: How can I properly type-hint methods in different files that would lead to circular imports? I eventually also found out that the `typing` module has a global variable `TYPECHECKING` that can be used to only import during type-checking.

How can I properly type-hint methods in different files that would lead to circular imports? I am writing a Python package where I have two classes in different files that (indirectly) depend on each other. If I wouldn't care about type-hints, there would be no problem, but unfortunately, I do like static type-hinting. Therefore, I need one class for typing the methods of the other and vic... (more) |
