List all files touched by commits in git

Asked 2022-Mar-25 at 08:24

How to list all the files that were "touched" somewhere between two commits? I am looking for a command similar to git diff COMMIT1..COMMIT2 --name-only but including the files that were modified and reverted later.

For example, let's say I have a repository with a series of commits (linear history): C0<-C1<-C2<-C3<-C4. The commit C1 introduced a new file F and then the commit C3 removed it from the repository. I am looking for a command that, given C0 and C4, would tell me that somewhere in between there was a file F. Even though there is no such file in C0 and in C4. Therefore git diff wouldn't mention file F at all.

git diff ref1 ref2 takes into account only given commits, yes, but git log will find the missing steps and list files for each one, which sort will aggregate :

QUESTION

Convolution Function Latency Bottleneck

Asked 2022-Mar-10 at 13:57

I have implemented a Convolutional Neural Network in C and have been studying what parts of it have the longest latency.

Based on my research, the massive amounts of matricial multiplication required by CNNs makes running them on CPUs and even GPUs very inefficient. However, when I actually profiled my code (on an unoptimized build) I found out that something other than the multiplication itself was the bottleneck of the implementation.

After turning on optimization (-O3 -march=native -ffast-math, gcc cross compiler), the Gprof result was the following:

Clearly, the convolution2D function takes the largest amount of time to run, followed by the batch normalization and depthwise convolution functions.

The convolution function in question looks like this:

Looking at the result of Cachegrind, it doesn't look like the memory is your bottleneck. The NN has to be stored in memory anyway, but if it's too large that your program's having a lot of L1 cache misses, then it's worth thinking to try to minimize L1 misses, but 1.7% of L1 (data) miss rate is not a problem.

So you're trying to make this run fast anyway. Looking at your code, what's happening at the most inner loop is very simple (load-> multiply -> add -> store), and it doesn't have any side effect other than the final store. This kind of code is easily parallelizable, for example, by multithreading or vectorizing. I think you'll know how to make this run in multiple threads seeing that you can write code with some complexity, and you asked in comments how to manually vectorize the code.

I will explain that part, but one thing to bear in mind is that once you choose to manually vectorize the code, it will often be tied to certain CPU architectures. Let's not consider non-AMD64 compatible CPUs like ARM. Still, you have the option of MMX, SSE, AVX, and AVX512 to choose as an extension for vectorized computation, and each extension has multiple versions. If you want maximum portability, SSE2 is a reasonable choice. SSE2 appeared with Pentium 4, and it supports 128-bit vectors. For this post I'll use AVX2, which supports 128-bit and 256-bit vectors. It runs fine on your CPU, and has reasonable portability these days, supported from Haswell (2013) and Excavator (2015).

The pattern you're using in the inner loop is called FMA (fused multiply and add). AVX2 has an instruction for this. Have a look at this function and the compiled output.

Input 0 of layer "model" is incompatible with the layer: expected shape=(None, 512, 512, 3), found shape=(512, 512, 3)

Asked 2022-Mar-08 at 14:22

I am training a Unet segmentation model for binary class. The dataset is loaded in tensorflow data pipeline. The images are in (512, 512, 3) shape, masks are in (512, 512, 1) shape. The model expects the input in (512, 512, 3) shape. But I am getting the following error. Input 0 of layer "model" is incompatible with the layer: expected shape=(None, 512, 512, 3), found shape=(512, 512, 3)

Use train_batches in model.fit and not train_images. Also, you do not need to use repeat(), which causes an infinite dataset if you do not specify how many times you want to repeat your dataset. Regarding your labels error, try rewriting your model like this:

Make the distance between neighbor notes the same (Theremin like app)

Asked 2021-Dec-24 at 13:44

I'm making a Theremin-like app in Unity (C#).

I have horizontal Axis X, on which I can click (with a mouse or with a finger on a smartphone). This X-axis determines the frequency, which will be played. The user will specify the frequency range of the board (X-Axis), let's say from frequency 261.63 (note C4) to 523.25 (note C5).

I'll calculate x_position_ratio which is a number between 0 and 1 determining, where did the user click on the X-axis (0 being on the most left (note C4 in this example), 1 on the most right (note C5))

From this, I will calculate the frequency to play by equation

Why can Record equal Functions?

ANSWER

Answered 2021-Dec-17 at 17:54

Record is special cased for assignability and it basically means any object type. This is explained in this GitHub issue

Normally the source type must have an index signature if the target type does, but for : any there's really nothing implied by this (every property must match any, by definition), so we made [s: string]: any a no-op for assignability reasons. This enabled some patterns that didn't work before:

Filtering a mutli-index

Asked 2021-Dec-14 at 11:55

C1 C2 C3 C4 A 12 True 89 9 False 77 5 True 23 B 9 True 45 5 True 45 2 False 78 C 11 True 10 8 False 08 12 False 09

C1 & C2 are the multi index. I'm hoping to get a result which gives me only values in C1 which have values both lower than 10 and greater than or equal to 10 in C2.

So in the table above C1 - B should go, with the final result should look like this:

C1 C2 C3 C4 A 12 True 89 9 False 77 5 True 23 C 11 True 10 8 False 08 12 False 09

I tried df.loc[(df.C2 < 10 ) & (df.C2 >= 10)] but this didn't work.

I also tried:

filter1 = df.index.get_level_values('C2') < 10 filter2 = df.index.get_level_values('C2') >= 10

df.iloc[filter1 & filter2]

Which I saw suggested on another post that also didn't work. Any one know how to solve this? Thanks
