kandi X-RAY | ad Summary

ad is a Python library typically used in Institutions, Learning, Education, Utilities, Math applications. ad has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can download it from GitHub.

The `ad` package allows you to easily and transparently perform first and second-order automatic differentiation. Advanced math involving trigonometric, logarithmic, hyperbolic, etc. functions can also be evaluated directly using the `admath` sub-module. All base numeric types are supported (`int`, `float`, `complex`, etc.). This package is designed so that the underlying numeric types will interact with each other as they normally do when performing any calculations. Thus, this package acts more like a "wrapper" that simply helps keep track of derivatives while maintaining the original functionality of the numeric calculations.

            Elastic beanstalk deploy fails when deploying more than 4 containers using docker compose
            Asked 2021-Jun-16 at 03:01

            I am having this weird issue with elastic beanstalk. I am using docker compose to run multiple docker containers on same elastic beanstalk instance.

            if I run 4 docker containers everything works fine. but if i make it 5, deploy fails with error Instance deployment failed to download the Docker image. The deployment failed. and if I check eb-engine.log. it retries to docker pull command and fails with error.

            this is really weird error. bcs all docker images are valid and correctly tagged. it just the number of services that I am adding in docker compose file. if number is greater than 4, deploy fails

            my question is, is there any limit of docker services that can be run using docker compose ? or is there any timeout in elastic beanstalk to pull images?

            Based on the comments.

            The issue was that t2.micro instance was used. The instance has only 1 vCPu and 1GB of ram. This was not enough to run 5 docker containers. Changing instance type to t2.large with 8GB ram and 2 vCPUs solved the problem.

            docker-compose allows to specify cpu and memory limits. Maybe you can set them up to keep your containers resource requirements in check.

            What is the best practice of passing reference counted C++ objects to Lua?
            Asked 2021-Jun-16 at 02:17

            I want to have my reference counted C++ object also managed in Lua callbacks: when it is held by a Lua variable, increase its refcount; and when the Lua variable is destroyed, release one refcount. It seems the releasing side can be automatically performed by __gc meta-method, but how to implement the increasing side?

            Is it proper&enough to just increase refcount every time before adding the object to Lua stack?

            Or maybe I should new a smart pointer object, use it everywhere in Lua C function, then delete it in __gc meta-method? This seems ugly as if something wrong with the Lua execution and the __gc is not called, the newed smart pointer object will be leaked, and the refcounted object it is referring would have leak one count.

            In Perl that I'm more familiar with, this can be achieved by increase refcount at OUTPUT section of XS Map, and decrease refcount at destroyer.

            If you are using vuetify from vue-cli-plugin-vuetify (vue add vuetify), treeshaking and auto component import is enabled by default, by using vuetify-loader.

            If you look into the source code of vue-cli-plugin-vuetify, it only uses vuetify-loader if it is present in your package.json. So removing vuetify-loader from package.json should disable this behavior.

Here is the docs for this approach https://docs.microsoft.com/en-us/azure/azure-functions/durable/durable-functions-sub-orchestrations?tabs=csharp Example from docs seem to be alike to yours.

By the time that the get request loads, my graph has populated with no data.
