機械学習のモデルを デプロイするのは 難しいですか？

@la t

Your model is too big for mobile deployment, so you’ll have to deploy it on the server side. Hook it up to our existing rails architecture and give me an API endpoint I can call with JSON requests. I’ll be sending you a couple thousand requests per second, so make sure the latency is below 150ms. Ask @in c if you get stuck. @ap c

@ap c said you’re using Python. Well then, you have to make a django or flask app and run it on nginx via wsgi. Make sure you have the right versions of cuda and cudnn in your docker environment. Provision a P2 instance on EC2 on and put your files in S3 with the right ACLs. You may need a load balancer so let me know if you need help calibrating the field polarity of the auxiliary neutron flow capacitors... @in c
