问题 We have several EC2 instances that are in a private subnet, but gets a public IP address every time that instance is launched. That private subnet has "Auto-assign Public IP" property set to No, but what happens is when instance was created, it got AssociatePublicIpAddress property set to true. Now we don't know how to reset AssociatePublicIpAddress to false without terminating the instances. I'd expect aws ec2 create-network-interface would have an option for that, but it's not the case.

问题 I want to decrease training time of my models by using a high end EC2 instance. So I tried c5.18xlarge instance with 2 CPUs and run a few models with parameter n_jobs=-1 but I noticed that only one CPU was utilized: Can I somehow make Scikit-learn to use all CPUs? 回答1: Try adding: import multiprocessing multiprocessing.set_start_method('forkserver') at the top of your code, before running or importing anything. That's a well-known issue with multiprocessing in python. 来源： https:/

问题 I am attempting to create my own bastion host for a VPC, and created an auto-scaling group with min/max instances of 1. In my launch configurations, I specify the following for the ec2 user data: #! INSTANCE_ID=`/usr/bin/curl -s http://169.254.169.254/latest/meta-data/instance-id` aws ec2 associate-address --instance-id $INSTANCE_ID --allocation-id eipalloc-my-eip-id --allow-reassociation The goal of this user data is to immediately associate an Elastic IP address with my newly created EC2

问题 The AWS EC2 Security Groups documentation mentions that "Security groups for EC2-VPC have additional capabilities that aren't supported by security groups for EC2-Classic" but the Security Groups dashboard does not provide any information on the "capabilities" of attributes of Security Groups that allow me to distinguish what kind of Security Group I'm looking at or what it is attached to, so that, for example I can't figure out whether I can consolidate Security Groups and share them across

问题 Description I have an AWS ec2 instance (ubuntu 16) that runs a Python application. In which I call some Facebook Account Kit APIs and also Google Play Store APIs. They all work perfectly fine until I reboot the instance two weeks before. After the reboot, the requests take more than 5 mins to finish, which is totally not acceptable. I have to manually set the timeout to over 10mins in order to let the request to be finished. The problem only occurs on one of my servers, I run with the same

问题 I am working on a Online Judge code checker.My code uses multi-threading in python 2.7.The same program on my local machine (i core 3 RAM 4GB) evaluates about 1000 submisions in 1 minute 10 seconds. But when I run it on ec2 micro instance(about 600 MB RAM) it takes about 40 minutes(It gets slow for some random seconds).To know the reason I broke down things. First this is how my evaluator works: I have a main program worker.py , which creates multiple threads The main thread pulls submissions
