Theano 0.8.2(2016年4月21日)

这是一个小版本的发布,只支持cudnn v5卷积和小修复。

亮点: - cuDNN v5卷积支持(cuDNN v3不再支持) - 修复几个崩溃

Theano 0.8.1(2016年3月29日)

这是一个没有任何新功能的小版本的发布。

It fixes compilation issues on MacOS X with the command line tools for XCode 7.3, which was released shortly after Theano 0.8.0.

Theano 0.8(2016年3月21日)

We recommend that everybody update to this version.

Highlights:
  • Python 2 and 3 support with the same code base
  • Faster optimization
  • Integration of cuDNN for better GPU performance
  • 许多Scan改进(执行速度,...)
  • optimizer=fast_compile moves computation to the GPU.
  • Better convolution on CPU and GPU. (CorrMM, cudnn, 3d conv, more parameter)
  • Interactive visualization of graphs with d3viz
  • cnmem (better memory management on GPU)
  • BreakpointOp
  • Multi-GPU for data parallism via Platoon (https://github.com/mila-udem/platoon/)
  • More pooling parameter supported
  • Bilinear interpolation of images
  • New GPU back-end:
    • Float16 new back-end (need cuda 7.5)
    • Multi dtypes
    • Multi-GPU support in the same process

Installation:
  • Better BLAS detection
  • 针对最新的软件和操作系统版本的修复
  • Support Anaconda on Windows
Bug fixes:
  • GpuJoin now supports negative axis
  • Fix GpuCumsum for negative axis
废弃的接口(会打印一个警告):
  • 不再使用Param类,改用In
Interface Changes:
  • 将DownsampleFactorMax重命名为Pool。
  • tensor.stack now uses the same interface as numpy.stack
  • optimizer=fast_compile moves computation to the GPU
  • Raise the user stack trace more frequently.
  • 更改开发版本编号以遵循PEP 440
New Interface (reuses existing functionality):
  • theano.tensor.nnet.relu
  • theano.tensor.nnet.elu
  • BatchNormalization.
  • MaxAndArgmax支持axis=None
  • Add theano.tensor.compress (equivalent of numpy.compress)
  • theano.tensor.signal.downsamples.max_pool_2d_same_size
  • COp
  • __props__
New features
  • tensor.unique
  • map_variables
  • erfcx
  • mgrid, ogrid
  • allclose
  • BreakpointOp
  • 使bincount在GPU上工作
  • GPU上的SolveOp
  • remove_all_assert可选的优化
  • AllocEmpty
  • LogSoftmax, for stability optimization when the crossentropy optimization does not apply.
  • theano.tensor.repeat works on GPU
  • BatchedDot on the GPU and faster on the CPU.
  • Faster batched_tensordot and make it work on GPU.
  • SoftmaxGrad grad
  • 通过CorrMM在GPU上进行3D转换
  • CPU Max Pool支持padding和strides!=windows的大小
  • theano.function() now accepts a dict for the outputs. When doing this, the function will return a dict. Helpful to keep track of which output is what.
  • Warn for unknown or misspelled theano config variables
  • theano.tensor.tile update (accept symbolic reps, work on GPU)
  • scan how have a strict flag. If set to True, this make scan building faster and could make execution faster.
  • theano.tensor.signal.conv2d(2d,2d)输出2d结果
  • More convolution parameter supported
  • Bilinear interpolation of images
Speed-ups:
  • Faster SetSubtensor on the GPU.
  • Support more reduction pattern on the GPU.
  • More graph optimization
  • Faster graph optimization
  • GpuCrossentropySoftmaxArgmax1HotWithBias
Crash/no return fixes:
  • Fix crash in the assert op grad
  • Fix curand crash on Mac
  • Multiple Fix scan crashes
  • Finish to update all Op.grad() implementation to the new interface
Others:
  • Support ARM processor.
  • Better tests
  • Code clean up.
  • Doc updates
  • doctest and sphinx test in travis
  • More tests tagged as slow
  • Better same_shape implementation
  • More op with c code to lower overhead
  • Custom pickler for SharedVariable theano.misc.pkl_utils. {dump,load}
  • function_dump to help us reproduce user error during compilation
  • assert_no_cpu_op
  • pep8, flake8
  • Better error messages
  • On non-default modes, reduce the number of allocation when allow_gc=False
  • Better lock
