kandi X-RAY | SAM Summary
The SAM Open Source Project repository contains the source code, tools, and instructions to build a desktop version of the National Renewable Energy Laboratory's System Advisor Model (SAM). SAM is a simulation program for electricity generation projects. It has models for different kinds of renewable energy systems and financial models for residential, commercial, and utility-scale projects. For more details about SAM's capabilities, see the SAM website at For a short video describing the SAM repositories, see The SAM release notes are in

QUESTION
I am trying to get a Flask and Docker application to work but when I try and run it using my docker-compose up
command in my Visual Studio terminal, it gives me an ImportError called ImportError: cannot import name 'json' from itsdangerous
. I have tried to look for possible solutions to this problem but as of right now there are not many on here or anywhere else. The only two solutions I could find are to change the current installation of MarkupSafe and itsdangerous to a higher version: https://serverfault.com/questions/1094062/from-itsdangerous-import-json-as-json-importerror-cannot-import-name-json-fr and another one on GitHub that tells me to essentially change the MarkUpSafe and itsdangerous installation again https://github.com/aws/aws-sam-cli/issues/3661, I have also tried to make a virtual environment named veganetworkscriptenv
to install the packages but that has also failed as well. I am currently using Flask 2.0.0 and Docker 5.0.0 and the error occurs on line eight in vegamain.py.
Here is the full ImportError that I get when I try and run the program:
...ANSWER
Answered 2022-Feb-20 at 12:31I was facing the same issue while running docker containers with flask.
I downgraded Flask
to 1.1.4
and markupsafe
to 2.0.1
which solved my issue.
Check this for reference.

QUESTION
consider a SAM defined in Java
...ANSWER
Answered 2022-Jan-03 at 18:28I've found some kind of a rationale in a comment in KT-7770:
... treating all the applicable interfaces as SAM might be too unexpected/implicit: one having a SAM-applicable interface may not assume that it will be used for SAM-conversions. Thus, adding another method to the interface becomes more painful since it might require changing syntax on the call sites (e.g. transforming callable reference to object literal).
Because of it, current vision is adding some kind of modifier for interfaces that when being applied:
- Adds a check that the interface is a valid SAM
- Allows SAM-conversions on call sites for it
Something like this:

I have created a SAM template with a function in it. After deploying SAM the lambda function gets added and are also displayed while adding lambda function trigger in cognito but when I save it gives a 404 error.
SAM template

QUESTION
I'm learning SAM, and I created two projects.
The first one, example1, I created it from the AWS web console, by going to Lambda, Applications, and choosing this template:
After the wizard finishes creating the app, it looks like this:
I'm interested in the yellow-highlighted area because I don't understand it yet.
I tried to replicate this more or less manually by using sam init
and created example2. It's easy to look at the template.yml
it creates and see how the stuff in Resources are created, but how is the stuff in Infrastructure created.
When I deploy example2 with sam deploy --guided
, indeed there's nothing in Infrastructure:
Given example2, how should I go about creating the same infrastructure as example1 had out of the box (and then changing it, for example, I want several environments, prod, staging, etc). Is this point and click in the AWS console or can it be done with CloudFormation?
I tried adding a permission boundary to example2, on of the things example1 has in Infrastructure, I created the policy in IAM (manually, in the console), added it to the template.yml
, and deployed it but it didn't show up in "Infrastructure".
ANSWER
Answered 2021-Dec-15 at 15:33Edit :
If I understand correctly, you want to reproduce the deployment on the SAM app. If that's the case, there is an AWS sample that covers the same approach.
It seems you are using either CodeStar/CodeCommit/CodePipeline/CodeDeploy/Code... etc. from AWS to deploy your SAM application on example1
.
At deploy time, these resources under infrastructure
are created by the "Code" services family in order to authorize, instantiate, build, validate, store, and deploy your application to CloudFormation.
On the other hand, on example2
, whenever you build your project in your local machine, both instantiation, build, validation, storage (of the upload-able built artifacts) are leveraged by your own device, hence not needed be provisioned by AWS.
To shortly answer your question: No. Your can't recreate these infrastructure resources on your own. But again, you wouldn't need to do so while deploying outside of AWS' code services.

I'm coming from Java and am new to Kotlin. I try to understand how to use receiver type with lambdas specified as functional SAM interfaces.
Let the code speak for itself.

Answered 2021-Dec-02 at 12:14You can define the functions inside the Delegator
as extension function, this way the receiver is passed as this
to the lambda.
QUESTION
#include
int main()
{
typedef union{
int a ;
char c;
float f;
} myu;
myu sam;
sam.a = 10;
sam.f=(float)5.99;
sam.c= 'H';
printf("%d\n %c\n %f\n",sam.a,sam.c,sam.f);
return 0;
}
...ANSWER
Answered 2021-Nov-30 at 15:19The fields of a union
all share the same starting memory address. This means that writing to one member will overwrite the contents of another.
When you write one member and then read a different member, the representation of the written member (i.e. how it is laid out in memory) is reinterpreted as the representation of the read member. Integers and floating point types have very different representations, so it makes sense that reading a float
as though it were an int
can vary greatly.
Things become even more complicated if the two types are not the same size. If a smaller field is written and a larger field is read, the excess bytes might not have event been initialized.
In your example, you first write the value 10 to the int
member. Then you write the value 5.99 to the float
member. Assuming int
and float
are both 4 bytes in length, all of the bytes used by the int
member are overwritten by the float
member.
When you then change the char
member, this only changes the first byte. Assuming a float
is represented in little-endian IEEE754, this changes just the low-order byte of the mantissa, so only the digits furthest to the right are affected.
QUESTION
First, I must mention that I am using Excel for Mac, so any code suggestions needs to work for a Mac using Office 365.
I have a large dataset that has nine columns of names. I want to delete the entire row if the same name is in multiple columns in the same row
Example dataset:
So all of these rows would be deleted because:
Jason
appearstwice
in row1
Jason
appears3
times in row2
Jason
appears4
times in row3
Sam
appearstwice
in row4
Fred
appears3
times in row5
So no matter how many times a name is repeated in the same row of data, I want to delete that entirerow.
My code is below. This code works but it crashes with a large dataset. I know there has to be a faster, more efficient way to write this code so that it can handle a large dataset. Plus, my code is too repetitive. There has to be a way to make the code more simple. Anyway, here's the code.
