QUESTION
While studying OpenCV, I realized that whenever I blend two images the colors of scr2 have changed in some way(depends on the colors of scr1).
I know this is not an informative and clear way to explain my issue, however; I don't know how to describe this issue since I have no expertise with colors so I would like to show you what I meant with images and code.
The input image: Input image
...ANSWER
Answered 2021-Jun-15 at 16:46I think I misunderstood your issue. If your issue is that the image where you do not have lines has changed, then that is because you used a white background for scr2. The white then mixes with your image in the output. Make it scr2=img.copy() in place of what you have now. Then try your code. So in Python/OpenCV as a demonstration, using the Lena image as background, here is your code:
QUESTION
I have run a topology, and I used the Meter type in metric Reporting API v2. In the execute method I mark this metric. So it will mark an event whenever the execute method is called. But when I compare this value with the __execute-count, I see huge differences. Does anyone know why this happens?
These are the values from my log which are gathered at the same time:
9:v7 __execute-count {v0:v7=44500}
9:v7 tuple_inRate.count 664129
Update: When I use the mark method on the Meter metric, I will get different results in comparison with the Counter metric. But still, I do not understand why the values from the counter metric (tuple counter) are not the same as the __execute-count.
...ANSWER
Answered 2021-Jun-11 at 06:51As given in this answer, Storms Internal Metrics are just estimated by a percentage of the real data flow. Initially, it uses 5% of incoming tuples to make those estimations. This may lead to inaccuracies for extreme high or low throughputs.
EDIT: The documentation describes the following:
In general all of these tuple count metrics are randomly sub-sampled unless otherwise stated. This means that the counts you see both on the UI and from the built in metrics are not necessarily exact. In fact by default we sample only 5% of the events and estimate the total number of events from that. The sampling percentage is configurable per topology through the topology.stats.sample.rate config. Setting it to 1.0 will make the counts exact, but be aware that the more events we sample the slower your topology will run (as the metrics are counted in the same code path as tuples are processed). This is why we have a 5% sample rate as the default.
EDIT 2 In this post, there is more information about the estimation:
The way it works is that if you choose a sampling rate of 0.05, it will pick a random element of the next 20 events in which to increase the count by 20. So if you have 20 tasks for that bolt, your stats could be off by +-380.
By the way, execute_count
is just an increasing number, while your tuple_inRate.count
is a rate, isn`t it?

QUESTION
I have a question about how rebasing works in git, in part because whenever I ask other devs questions about it I get vague, abstract, high level "architect-y speak" that doesn't make a whole lot of sense to me.
It sounds as if rebasing "replays" commits, one after another (so sequentially) from the source branch over the changes in my working branch, is this the case? So if I have a feature branch, say, feature/xyz-123
that was cut from develop
originally, and then I rebase from origin/develop
, then it replays all the commits made to develop
since I branched off of it. Furthermore, it does so, one develop
commit at a time, until all the changes have been "replayed" into my feature branch, yes?
If anything I have said above is incorrect or misled, please begin by correcting me! But assuming I'm more or less correct, I'm not seeing how this is any different than merging in changes from develop
by doing a git merge develop
. Don't both methods result with all the latest changes from develop
making their way into feature/xyz-123
?
I'm sure this is not the case but I'm just not seeing the forest through the trees here. If someone could give a concrete example (with perhaps some mock commits and git command line invocations) I might be able to understand the difference in how rebase works versus a merge. Thanks in advance!

Yes.
" Furthermore, it does so, one develop commit at a time, until all the changes have been "replayed" into my feature branch, yes? "
No, it's the contrary. If you rebase your branch on origin/develop
, all your branch's commits are to be replayed on top of origin/develop
, not the other way around.
Finally, the difference between merge and rebase scenarios has been described in details everywhere, including on this site, but very broadly the merge workflow will add a merge commit to history. For that last part, take a look here for a start.

QUESTION
Machine Setting:
GPU: GeForce RTX 3060
Driver Version: 460.73.01
CUDA Driver Veresion: 11.2
Tensorflow: tensorflow-gpu 1.14.0
CUDA Runtime Version: 10.0
cudnn: 7.4.1
Note:
- CUDA Runtime and cudnn version fits the guide from Tensorflow official documentation.
- I've also tried for TensorFlow-gpu = 2.0, still the same problem.
Problem:
I am using Tensorflow for an objection detection task. My situation is that the program will stuck at
2021-06-05 12:16:54.099778: I tensorflow/stream_executor/platform/default/dso_loader.cc:42] Successfully opened dynamic library libcublas.so.10
for several minutes.
And then stuck at next loading process
2021-06-05 12:21:22.212818: I tensorflow/stream_executor/platform/default/dso_loader.cc:42] Successfully opened dynamic library libcudnn.so.7
for even longer time. You may check log.txt for log details.
After waiting for around 30 mins, the program will start to running and WORK WELL.
However, whenever program invoke self.session.run(...)
, it will load the same two library related to cuda (libcublas and libcudnn) again, which is time-wasted and annoying.
I am confused that where the problem comes from and how to resolve it. Anyone could help?
===================================
Update
After @talonmies 's help, the problem was resolved by resetting the environment with correct version matching among GPU, CUDA, cudnn and tensorflow. Now it works smoothly.
...ANSWER
Answered 2021-Jun-15 at 13:04Generally, if there are any incompatibility between TF, CUDA and cuDNN version you can observed this behavior.
For GeForce RTX 3060
, support starts from CUDA 11.x
. Once you upgrade to TF2.4
or TF2.5
your issue will be resolved.

QUESTION
I have an object of class Employee (let us call it Alice), and want to create a copy of this object (let us call it Alice_again) such that if I change Alice, the properties of Alice_again also changes. Basically creating a copy of an object whose properties are bound to the original.
Edits
I am having two diferent ObservableCollection of Employee(Employee is User Control) and both contains same object Employee and I want to display each ObservableCollection once. For that I am using ItemsControl and I have binded ItemsSource of ItemsControl to these ObservableCollection and as I have read on this link that a given object may only be present in a given logical tree once, so I am trying to create a copy of object but I don't want to update both copies whenever there is an update.
...ANSWER
Answered 2021-Jun-15 at 10:22You do not need to create a copy.
Since the elements in the ItemsSource collection are not supposed to be Visuals, two or more source collections may contain references to the same objects.
Two different UI elements in the ItemTemplate of two ItemsControl would hence legitimately bind to the same data item object.
