Limits of EAIS instances-阿里云帮助中心

This topic describes the limits that apply to Elastic Accelerated Computing Instances (EAIS).

Limit	Limitations
User identity	You must complete identity verification to create EAIS instances.
Account balance	To enable pay-as-you-go EAIS resources, your Alibaba Cloud account balance, which includes your cash balance and coupons, must be at least CNY 100.00.
Inference framework	Only TensorFlow and PyTorch frameworks are supported for inference. Other frameworks are not supported.
Billing method	Only the pay-as-you-go billing method is supported.
Supported regions	EAIS is available in only five regions: China (Beijing), China (Hangzhou), China (Shanghai), China (Shenzhen), and China (Chengdu). International regions are not supported.
ECS instance type	An ECS instance must have at least 1 vCPU and 2 GiB of memory.
Bindings	An EAIS instance can be attached to only one ECS instance. The number of EAIS instances that can be attached to an ECS instance depends on the framework you use: TensorFlow: An ECS instance can be attached to only one EAIS instance. PyTorch: An ECS instance can be attached to one or more EAIS instances, up to a maximum of 256.
Region	The ECS instance and the EAIS instance to be attached must be in the same zone of the same region. Important You cannot specify a zone when you create an EAIS instance. To ensure the ECS instance and the EAIS instance are in the same zone, deploy them on the same vSwitch.
Network	The ECS instance and the EAIS instance to be attached must be in the same vSwitch of the same virtual private cloud (VPC).
