kandi X-RAY | serving Summary
TensorFlow Serving is a flexible, high-performance serving system for machine learning models, designed for production environments. It deals with the inference aspect of machine learning, taking models after training and managing their lifetimes, providing clients with versioned access via a high-performance, reference-counted lookup table. TensorFlow Serving provides out-of-the-box integration with TensorFlow models, but can be easily extended to serve other types of models and data.

QUESTION
I have swagger (docker: swaggerapi/swagger-ui) running on swagger.mydomain.com with two definitions for api servers running on a.mydomain.com and b.mydomain.com
Both a and b are flask (python) servers. a.mydomain.com had CORS set up for a while now due to serving a webapp on a fourth subdomain. This works fine both on that subdomain, as well as in swagger. Now I did the same CORS setup for b.mydomain.com, however without success.
The setup on both servers looks like this:
...ANSWER
Answered 2021-Sep-17 at 23:52A 400 is a pretty unusual response code for a preflight response. That suggests the endpoint might be configured to expect a certain request body/payload or headers in the request regardless of what the HTTP method is for the request. But since for the preflight OPTIONS request, the browser sends no request body and no additional header, the server code is not receiving what it expects.
For such cases, the fix is to ensure you have a specific, separate handler for OPTIONS requests configured for that route/endpoint.
QUESTION
Since upgrading to version 2.14.5 of the Cosmos DB emulator, I'm seeing high CPU usage by what appears to be the tray icon process (Microsoft.Azure.Cosmos.Emulator.exe). See below, using up most of a CPU core constantly on an Intel i9-12900K. This was an upgrade from 2.14.4 on Windows 11.
Anyone from the emulator team know what might be going on? Seems like the process is doing something silly, given the system is otherwise quiet and the process is not actually doing anything related to serving requests.
Also worth noting is that opening the "About Azure Cosmos Emulator" dialog immediately drops the CPU usage to 0. When closing the dialog, usage jumps back.

I am implementing a simple chatbot using keras and WebSockets. I now have a model that can make a prediction about the user input and send the according answer.
When I do it through command line it works fine, however when I try to send the answer through my WebSocket, the WebSocket doesn't even start anymore.
Here is my working WebSocket code:
...ANSWER
Answered 2022-Feb-16 at 19:53There is no problem with your websocket route. Could you please share how you are triggering this route? Websocket is a different protocol and I'm suspecting that you are using a HTTP client to test websocket. For example in Postman:
HTTP requests are different than websocket requests. So, you should use appropriate client to test websocket.

PS: Is it not a research kind of question! I have been trying to do this from very long time.
I am trying to make web based an image editor where user can select multiple cropping area and after selection save/download all the image area. like below.
As of now I discovered two libraries
1.Cropper.JS where is only single selection feature is available.
2.Jcrop where only single selection area restrictions.
I am currently using cropper.Js but it seems impossible for me to make multiple selection cropping. Any help is much appreciated.if any other method/library available in JavaScript, Angular or PHP or reactJS for multiple image area selection and crop and download in one go as in the image below.

I'm using Go v1.17.3
I'm pretty new with Go and coming from an OOP background I'm very aware I'm not in the Gopher mindset yet! So I've split the question in 2 sections, the first is the problem I'm trying to solve, the second is what I've done so far. That way if I've approached the solution in a really strange way from what idiomatic Go should look like the problem should still be clear.

QUESTION
I've been trying to get over this but I'm out of ideas for now hence I'm posting the question here.
I'm experimenting with the Oracle Cloud Infrastructure (OCI) and I wanted to create a Kubernetes cluster which exposes some service.
The goal is:
- A running managed Kubernetes cluster (OKE)
- 2 nodes at least
- 1 service that's accessible for external parties
The infra looks the following:
- A VCN for the whole thing
- A private subnet on 10.0.1.0/24
- A public subnet on 10.0.0.0/24
- NAT gateway for the private subnet
- Internet gateway for the public subnet
- Service gateway
- The corresponding security lists for both subnets which I won't share right now unless somebody asks for it
- A containerengine K8S (OKE) cluster in the VCN with public Kubernetes API enabled
- A node pool for the K8S cluster with 2 availability domains and with 2 instances right now. The instances are ARM machines with 1 OCPU and 6GB RAM running Oracle-Linux-7.9-aarch64-2021.12.08-0 images.
- A namespace in the K8S cluster (call it staging for now)
- A deployment which refers to a custom NextJS application serving traffic on port 3000
And now it's the point where I want to expose the service running on port 3000.
I have 2 obvious choices:
- Create a LoadBalancer service in K8S which will spawn a classic Load Balancer in OCI, set up it's listener and set up the backendset referring to the 2 nodes in the cluster, plus it adjusts the subnet security lists to make sure traffic can flow
- Create a Network Load Balancer in OCI and create a NodePort on K8S and manually configure the NLB to the ~same settings as the classic Load Balancer
The first one works perfectly fine but I want to use this cluster with minimal costs so I decided to experiment with option 2, the NLB since it's way cheaper (zero cost).
Long story short, everything works and I can access the NextJS app on the IP of the NLB most of the time but sometimes I couldn't. I decided to look it up what's going on and turned out the NodePort that I exposed in the cluster isn't working how I'd imagine.
The service behind the NodePort is only accessible on the Node that's running the pod in K8S. Assume NodeA is running the service and NodeB is just there chilling. If I try to hit the service on NodeA, everything is fine. But when I try to do the same on NodeB, I don't get a response at all.
That's my problem and I couldn't figure out what could be the issue.
What I've tried so far:
- Switching from ARM machines to AMD ones - no change
- Created a bastion host in the public subnet to test which nodes are responding to requests. Turned out only the node responds that's running the pod.
- Created a regular LoadBalancer in K8S with the same config as the NodePort (in this case OCI will create a classic Load Balancer), that works perfectly
- Tried upgrading to Oracle 8.4 images for the K8S nodes, didn't fix it
- Ran the Node Doctor on the nodes, everything is fine
- Checked the logs of kube-proxy, kube-flannel, core-dns, no error
- Since the cluster consists of 2 nodes, I gave it a try and added one more node and the service was not accessible on the new node either
- Recreated the cluster from scratch
Edit: Some update. I've tried to use a DaemonSet instead of a regular Deployment for the pod to ensure that as a temporary solution, all nodes are running at least one instance of the pod and surprise. The node that was previously not responding to requests on that specific port, it still does not, even though a pod is running on it.
Edit2: Originally I was running the latest K8S version for the cluster (v1.21.5) and I tried downgrading to v1.20.11 and unfortunately the issue is still present.
Edit3: Checked if the NodePort is open on the node that's not responding and it is, at least kube-proxy is listening on it.
...ANSWER
Answered 2022-Jan-31 at 12:06Might not be the ideal fix, but can you try changing the externalTrafficPolicy to Local. This would prevent the health check on the nodes which don't run the application to fail. This way the traffic will only be forwarded to the node where the application is . Setting externalTrafficPolicy to local is also a requirement to preserve source IP of the connection. Also, can you share the health check config for both NLB and LB that you are using. When you change the externalTrafficPolicy, note that the health check for LB would change and the same needs to be applied to NLB.
Edit: Also note that you need a security list/ network security group added to your node subnet/nodepool, which allows traffic on all protocols from the worker node subnet.
QUESTION
After updating my npm packages, some of the imports from the 'vue' module started showing errors:
TS2305: Module '"../../node_modules/vue/dist/vue"' has no exported member 'X'
where X is nextTick, onMounted, ref, watch etc. When serving the project, Vue says it's "failed to compile". WebStorm actually recognizes the exports, suggests them and shows types, but the error is shown regardless. Some exports like computed and defineComponent work just fine.
What I've tried:
- Rollback to the previously used Vue version "3.2.2" > "3.0.11". It makes the abovementioned type errors disappear, but the app stops working entirely, showing lots of
TypeError: Object(...) is not a functionerrors in console and not rendering the app at all. In the terminal, some new warnings are introduced:"export 'X' (imported as '_X') was not found in 'vue'where X is createElementBlock, createElementVNode, normalizeClass and normalizeStyle. - Rollback other dependencies. None of the ones that I tried helped fix the problem, unfortunately.
- Manually declare the entirety of 'vue' module. We can declare the 'vue' module exports in shims-vue.d.ts, and it actually makes the errors disappear, however, this seems like a terrible, time-consuming workaround, so I would opt out for a better solution if possible.
My full list of dependencies:
...ANSWER
Answered 2021-Aug-15 at 13:53That named exports from composition API are unavailable means that vue is Vue 2 at some place which has only default export. Since Vue 3 is in dependencies and both lock file and node_modules were refreshed, this means that Vue 2 is nested dependency of some direct dependency.
The problem needs to be investigated in lock file. It shows that @vue/cli-plugin-unit-jest@4.5.13 depends on vue-jest@3 which depends on vue@2.
A possible solution is to upgrade @vue/cli-plugin-unit-jest to the latest version, next. The same likely applies to other @vue/cli-* packages because they have matching versions.
