I am trying to save an altered z-stack .tif file in Python3. Here's my code where I checked that the the functions worked as intended.
...ANSWER
Answered 2021-May-28 at 22:00It looks like you need to convert bdata type to np.uint8 and multiply the result by 255.
The type of the expression (adata < adata[0].mean()) is
np.bool.
The common image type isnp.uint8.
Convert(adata < adata[0].mean())to typenp.uint8:

Recentry CodePipeline introduced CloudFormation StackSet integration ( https://aws.amazon.com/about-aws/whats-new/2020/12/aws-codepipeline-supports-deployments-with-cloudformation-stacksets/ ). I'm trying to build a pipeline that deploys stack set but pipeline action fails with message:
An API call to CloudFormation.UpdateStackSet (RequestId: {ID}) returned a ValidationError error: You must provide an administration role ARN with the correct PassRole permission to perform an update operation on this StackSet.
The stack set is already there and the roles are working fine, I'm just trying to bind the deployment into CodePipeline using new integration feature (using same roles).
My pipeline role is allowed to pass stack set administration role:

Answered 2021-Jan-07 at 10:08This part all seems right, but I can't tell if you are making use of the CloudFormationStackSet Action
Also, you don't mention if it is being used with the organization. If this is the case, you need to enable it in your organizational settings.

...ANSWER
Answered 2020-Oct-20 at 06:57Assuming Image has values in the range 0-65535 (16bit)
to scale the values into an 8bit image:
- first divided the image by 65535 (2^16) - this will normalize value range to 0-1
- now you need to rescale to 8bit range of values, multiplying the image by 255
so basically:
QUESTION
This was a CodeStar project initially, and then it grew into something bigger. We reused the Beanstalk application to create the stage and prod environments and kept the initially-created dev environment as-is.
We updated the CodePipeline to deploy to our new environments using "Elastic Beanstalk" as the Provider. (While CodeStar had setup a deployment using CloudFormation for the environment it automatically provisioned in the Beanstalk application.)
The problemThe deployment fails due to an error which mentions autoscaling:DescribeAutoScalingGroups as not being authorized to be executed by the CodePipeline's IAM Role.
Here is the whole error message displayed in CodePipeline:
IAMInsufficient permissions
Deployment failed.
The provided role does not have sufficient permissions: User: arn:aws:sts::xxx:assumed-role/CodeStarWorker-xxx-on-cod-ToolChain/yyy is not authorized to perform: autoscaling:DescribeAutoScalingGroups (Service: AmazonAutoScaling; Status Code: 403; Error Code: AccessDenied; Request ID: 905ee6ef-d75d-4cf8-b5f3-e6b16a5f6477)

Answered 2020-Feb-29 at 19:45This is a tough one to troubleshoot, but from what I can see there are a couple of potential issues. One is that the 'DescribeAutoScalingGroups' action does not support a resource-level permission, so it must be an asterisk as the resource, and not the resource arn. You could try just removing the:
QUESTION
My problem is:
Livolo switches have their own Zigbee gate. I want to connect them from zigbee2mqtt with CC2531 USB dongle. In general it works, but when I turn on/off switch button (on physical device), the switch sends an incorrect ZCL package.
I'm an absolutely newbie in microcontrollers programming and in Zigbee architecture. So I hope someone can help me and answer these questions:
- Where I can intercept that malformed package?
- How I can fix that package to support the Zigbee standard?

QUESTION
I have n number of images with same size that need to be stacked along Z-Axis as shown in figure creating a sort of 3D Model. I have tried doing this using Z-Stack with different libraries (like here) then I need to create a top down view with of stacked images converting the 3D model into 2D image.
I have tried rotating each slice and making a TIFF-Z Stack out of it, but can not seem to make it work.
Total number of n Images (ABCD), each with size of H x W pixels would be stacked along Z-Axis like in figure creating a top down view ABFE with a size of W x n pixels.
ABFE is what i intend to achieve.
Since I am new to image processing, any help (also which terms to research after) would be much appreciated!

QUESTION
I'm actually making a program which recognised two PS3 controllers and blits images of them to screen, along with their controller names and other 'background sprites'. I want the users to click on a controller and a circle or such-like appears over THEIR controller - so they know which they have picked up, then when their buttons are released, the circle will disappear (or be drawn-over with all my background art to effectively delete the circles from the screen). I guess this background list and the way it doesn't appear to update the screen as I'd like is fundamental here...
To simplify this issue, I'm giving a related shorter example: I want to show the controllers as attached devices represented by a controller image, or in this shortened piece of code as white vertical lines. I have built up the background image using a list, bgd[]. When I press a button on either joystick, I am wishing to see a temporary grey line appear by the associated controller (white line), which should vanish when the key is lifted. My problem is I can't get the grey lines to vanish. I thought I simply needed to blit over everything with the contents of the unchanging background images bgd[].
...ANSWER
Answered 2018-Sep-23 at 07:35I'd check if the specific button is pressed in the main loop and then just draw the corresponding rect.
By the way, the reDraw function in your example doesn't draw anything. You would have to call pygame.draw.rect in the for loop, but then it would just draw several white rects. You could put [color, rect] lists into the bgd list instead of just the rects and then use a for loop to draw them.
Also, better create the joystick instances ahead of the main loop (you'd still need some checks in the main loop to prevent crashes if one of the joysticks doesn't exist).

ANSWER
Answered 2018-Jun-17 at 12:20Static in a global scope means it is only visible in that file. You're confusing it with static in a function I suspect. See this answer for details:
A global variable is implicitly the same as a static variable in a function, you don't need the static at the global scope in your code. You will then also want to define the variable using the extern keyword in your header file, as per:
How do I use extern to share variables between source files?
