QUESTION
I saw an answer to a question here. There the author of the answer made use of the fact that
exception specifications do not participate1 in template argument deduction.
In the answer linked above it is explained why the following doesn't compile:
...ANSWER
Answered 2022-Mar-17 at 13:25Here since there is no func, so during the substitution of the template argument(s) in the return type of the function template, we get substitution failure and due to SFINAE this function template is not added to the set. In other words, it is ignored.
Thus the call timer(5); uses the ordinary function timer since it is the only viable option now that the function template has been ignored. Hence the program compiles and gives the output:
QUESTION
I am trying to schedule a data-quality monitoring job in AWS SageMaker by following steps mentioned in this AWS documentation page. I have enabled data-capture for my endpoint. Then, trained a baseline on my training csv file and statistics and constraints are available in S3 like this:
...ANSWER
Answered 2022-Feb-26 at 04:38This happens, during the ground-truth-merge job, when the spark can't find any data either in '/opt/ml/processing/groundtruth/' or '/opt/ml/processing/input_data/' directories. And that can happen when either you haven't sent any requests to the sagemaker endpoint or there are no ground truths.
I got this error because, the folder /opt/ml/processing/input_data/ of the docker volume mapped to the monitoring container had no data to process. And that happened because, the thing that facilitates entire process, including fetching data couldn't find any in S3. and that happened because, there was an extra slash(/) in the directory to which endpoint's captured-data will be saved. to elaborate, while creating the endpoint, I had mentioned the directory as s3:////, while it should have just been s3:///. so, while the thing that copies data from S3 to docker volume tried to fetch data of that hour, the directory it tried to extract the data from was s3://////////(notice the two slashes). So, when I created the endpoint-configuration again with the slash removed in S3 directory, this error wasn't present and ground-truth-merge operation was successful as part of model-quality-monitoring.
I am answering this question because, someone read the question and upvoted it. meaning, someone else has faced this problem too. so, I have mentioned what worked for me. And I wrote this, so that StackExchange doesn't think I am spamming the forum with questions.

I'm trying to make a sort of cribbage game in Python, and it's actually going quite well. I've run into a problem though. Whenever I try to print the six 'cards' dealt to the player, it always prints them to 6 different lines. What would I need to use and how would I make it so they just print in one line right next to each other? My code is below:

QUESTION
I want to encrypt data in a web browser that is send to my C# backend and decrypted there.
That fails because I am unable to decrypt the data generated on the frontend in the backend.
Here's what I did so far.
First I created a private/public key pair (in XmlString Format). I took the ExportPublicKey function to generate the public key file from here: https://stackoverflow.com/a/28407693/98491
ANSWER
Answered 2022-Jan-24 at 15:42You need to encrypt with the private key and then decrypt with the public key

QUESTION
I'd like to execute some preprocessing like this diagram using sklearn's pipelines.
I can do this without any problems if I leave off the standardization step. But I cannot understand how to indicate that the output from the imputation step should flow to the standardization step.
Here is the current code without the standardization step:
...ANSWER
Answered 2022-Jan-17 at 18:22The fact is that ColumnTransformer applies its transformers in parallel to the dataset you're passing to it. Therefore if you're adding the transformer which standardizes your numeric data as the second step in your transformers list, this won't apply on the output of the imputation, but rather on the initial dataset.
One possibility to solve such problem is to enclose the transformations on the numeric columns in a Pipeline.
QUESTION
I am trying to write a program that compares single characters, but it says the buffer is not equal to 'S' even though I gave one as input, I know there comes a new-line and terminating sign after the input string but isn't [.buffer] just supposed to give the first character of the string?
...ANSWER
Answered 2022-Jan-15 at 16:36Continuing from the comment above, you comparison is failing because you are attempting to compare a single byte 'S' or 'Q' against an 8-byte register. That won't work. rdx has 7 other bytes that will not be 'S' or 'Q' and the test will fail every time.
Stepping each instruction in gdb makes it easy to see. Run gdb yourexecutable, then break _start to create a breakpoint at the program start. (for convenience display the current command being executed by setting display/i $pc) Now just use si to step-instruction through your code. When you get to your data entry and comparison, examine the contents of both .buffer and rdx, e.g.

void* aPtr = NULL; // we don't yet know what it points to.

aPtr = &height; // it has the address of height, but no type yet.

int h = (int)*aPtr; // with casting, we can now go to that address
// and fetch an integer value.

'with casting, we can now go [...]'
The question is - can we really?
Yes, but the shown code doesn't do any dereferencing. Well, it tries to dereference a void* and cast the result to int. That's not how it should be done. You must first cast to int* and then dereference that int*.

PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
