Dear users and developers,

After almost ten years of development, we have the regret to announce

that we will put an end to our Theano development after the 1.0 release,

which is due in the next few weeks. We will continue minimal maintenance

to keep it working for one year, but we will stop actively implementing

new features. Theano will continue to be available afterwards, as per

our engagement towards open source software, but MILA does not commit to

spend time on maintenance or support after that time frame.

The software ecosystem supporting deep learning research has been

evolving quickly, and has now reached a healthy state: open-source

software is the norm; a variety of frameworks are available, satisfying

needs spanning from exploring novel ideas to deploying them into

production; and strong industrial players are backing different software

stacks in a stimulating competition.

We are proud that most of the innovations Theano introduced across the

years have now been adopted and perfected by other frameworks. Being

able to express models as mathematical expressions, rewriting

computation graphs for better performance and memory usage, transparent

execution on GPU, higher-order automatic differentiation, for instance,

have all become mainstream ideas.

In that context, we came to the conclusion that supporting Theano is no

longer the best way we can enable the emergence and application of novel

research ideas. Even with the increasing support of external

contributions from industry and academia, maintaining an older code base

and keeping up with competitors has come in the way of innovation.

MILA is still committed to supporting researchers and enabling the

implementation and exploration of innovative (and sometimes wild)

research ideas, and we will keep working towards this goal through other

means, and making significant open source contributions to other projects.

Thanks to all of you who for helping develop Theano, and making it

better by contributing bug reports, profiles, use cases, documentation,

and support.

Head of MILA

亲爱的用户和开发者，

经过近十年的发展，我们很遗憾地宣布，在接下来的几周内发布1.0版本后，我们将结束对Theano的开发。我们将继续进行最低限度的维护，以确保其能够正常工作一年，但我们将停止积极实施新功能。Theano将继续可用，遵循我们对开源软件的承诺，但MILA不承诺在此时间段之后花费时间进行维护或支持。

支持深度学习研究的软件生态系统发展迅速，现在已经达到了健康状态：开源软件已成为常态；提供了各种框架，满足了从探索新颖想法到将其部署到生产中的需求；并且强大的工业参与者支持着不同的软件堆栈，形成了激烈的竞争。

我们自豪地宣布，Theano多年来引入的大部分创新现在已被其他框架采纳并完善。例如，能够将模型表达为数学表达式、重写计算图以获得更好的性能和内存使用、在GPU上透明地执行、高阶自动微分等，这些都已成为主流观念。

在这种情况下，我们得出结论：支持Theano不再是我们促进新型研究思想出现和应用的最佳方式。即使在工业界和学术界的外部贡献日益增多的情况下，维护旧代码库并与竞争对手保持一致已经阻碍了创新的发展。

MILA仍致力于支持研究人员，促进创新（有时可能是激进的）研究思想的实施和探索，并将通过其他方式继续努力实现这一目标，并向其他项目做出重大的开源贡献。

感谢所有帮助开发Theano并通过贡献错误报告、档案、用例、文档和支持使其变得更好的人们。

MILA负责人
