QUESTION

Apply a change to the last row of each group by ID in a dataframe

Asked 2022-Mar-18 at 17:20

For the next dataframe, I want to modify two columns for the last row of each cluster.

country ID counter direction ENG 0 1 OUT ENG 0 0 IN ESP 0 6 OUT ENG 1 5 IN ENG 1 5 IN FRA 2 4 OUT ENG 3 4 OUT

I want to obtain the following result:

country ID counter direction exit_to ENG 0 1 OUT NaN ENG 0 0 IN NaN ESP 0 7 OUT E ENG 1 5 IN NaN ENG 1 5 IN NaN FRA 2 4 OUT W ENG 3 4 OUT E

For the last row of each group, I increment the value of the counter column by 1 and create a new column exit_to, with value E if direction = OUT and country ESP. If the direction of the last row is OUT the column exit_to, takes the value of W if country = FRA and E if country = ENG and the counter in both cases stays the same.

For the behaviour of the exit_to column, I have implemented the following code.

There is no need to use apply, here we can use a vectorized solution with boolean indexing:

QUESTION

Calculates a standard deviation columns for timedelta elements

Asked 2022-Mar-15 at 17:07

I have the following dataframe in Python:

ID country_ID visit_time 0 ESP 10 days 12:03:00 0 ESP 5 days 02:03:00 0 ENG 5 days 10:02:00 1 ENG 3 days 08:05:03 1 ESP 1 days 03:02:00 1 ENG 2 days 07:01:03 2 ENG 0 days 12:01:02

For each ID I want to calculate the standard deviation of each country_ID group.

std_visit_ESP and std_visit_ENG columns.

standard deviation of visit time with country_ID = ESP for each ID.
standard deviation of visit time with country_ID = ENG for each ID.

ID std_visit_ESP std_visit_ENG 0 2 days 17:00:00 0 days 00:00:00 1 0 days 00:00:00 0 days 12:32:00 2 NaT 0 days 00:00:00

With the groupby method for the mean, you can specify the parameter numeric_only = False, but the std method of groupby does not include this option.

My idea is to convert the timedelta to seconds, calculate the standard deviation and then convert it back to timedelta. Here is an example:

QUESTION

Avoiding circular imports for the 100th time

Asked 2022-Feb-21 at 10:56

Summary

I keep on having an ImportError in a complex project. I've distilled it to the bare minimum that still gives the error.

Example

A wizard has containers with green and brown potions. These can be added together, resulting in new potions that are also either green or brown.

We have a Potion ABC, which gets its __add__, __neg__ and __mul__ from the PotionArithmatic mixin. Potion has 2 subclasses: GreenPotion and BrownPotion.

In one file, it looks like this:

ANSWER

Answered 2022-Feb-02 at 10:56

You somehow have to break the circle of the class dependencies. I haven't tried it out, but I think the following strategy might work. The idea is to construct the class PotionArithmatic first with no dependencies. Then you can inject the methods after the class has been fully constructed. But it is perhaps just as cumbersome as your solution:

QUESTION

Wrong result of multiplication: Undefined behavior or compiler bug?

Asked 2022-Feb-18 at 23:52

Background

While debugging a problem in a numerical library, I was able to pinpoint the first place where the numbers started to become incorrect. However, the C++ code itself seemed correct. So I looked at the assembly produced by Visual Studio's C++ compiler and started suspecting a compiler bug.

Code

I was able to reproduce the behavior in a strongly simplified, isolated version of the code:

sourceB.cpp:

ANSWER

Answered 2022-Feb-18 at 23:52

Even though nobody posted an answer, from the comment section I could conclude that:

Nobody found any undefined behavior in the bug repro code.
At least some of you were able to reproduce the undesired behavior.

So I filed a bug report against Visual Studio 2019.

The Microsoft team confirmed the problem.

However, unfortunately it seems like Visual Studio 2019 will not receive a bug fix because Visual Studio 2022 seemingly does not have the bug. Apparently, the most recent version not having that particular bug is good enough for Microsoft's quality standards.

I find this disappointing because I think that the correctness of a compiler is essential and Visual Studio 2022 has just been released with new features and therefore probably contains new bugs. So there is no real "stable version" (one is cutting edge, the other one doesn't get bug fixes). But I guess we have to live with that or choose a different, more stable compiler.

VBE: why does my code not provide a linear frame buffer?

Asked 2022-Jan-15 at 21:24

I am a beginner who is trying to implement simple graphics in VBE. I have written the following assembly code to boot, enter 32-bit protected mode, and enter VBE mode 0x4117. (I was told that the output of [mode] OR 0x4000 would produce a version of the mode with a linear frame buffer, so I assumed that 0x0117 OR 0x4000 = 0x4117 should have a linear frame buffer.

ANSWER

Answered 2022-Jan-15 at 21:24

Have I correctly loaded a linear frame buffer, and, if not, how could I do so?

In your code you just assume that the linear frame buffer mode is available. You should inspect the ModeInfoBlock.ModeAttributes bit 7 to know for sure. The bit needs to be ON:

ANSWER

Answered 2022-Jan-15 at 15:42

GCC does the same thing, using mov reg, imm32 / mov m16, reg instead of mov mem, imm16.

It's to avoid LCP stalls on Intel P6-family CPUs from 16-bit operand-size mov imm16.

An LCP (length changing prefix) stall occurs when a prefix changes the length of the rest of the instruction compared to the same machine code bytes without prefixes.

mov word ptr [ebp - 8], 11 would involve a 66 prefix that makes the rest of the instruction 5 bytes (opcode + modrm + disp8 + imm16) instead of 7 (opcode + modrm + disp8 + imm32) for the same opcode / modrm.)
