我正在使用安装了Theano库的Python 2.7(更新版本),我对输入参数有问题,定义了Theano函数.

代码是:

    corruption_level = T.scalar('corruption')  # % of corruption to use
    learning_rate = T.scalar('lr')  # learning rate to use

    fn = theano.function(
        inputs=[
            index,
            theano.In(corruption_level, value=0.2),
            theano.In(learning_rate, value=0.1)
        ],
        outputs=cost,
        updates=updates,
        givens={
            self.x: train_set_x[batch_begin: batch_end]
        }
    )

它取自这里:

它给了我这个错误,使用Eclipse:

NotImplementedError: In() instances and tuple inputs trigger the old
semantics, which disallow using updates and givens

所以,如果我以这种方式更改代码:

        fn = theano.function(
            inputs=[
                index,
                #theano.In(corruption_level, value=0.2),
                #theano.In(learning_rate, value=0.1)
                corruption_level,
                learning_rate
            ],
            outputs=cost,
            updates=updates,
            givens={
                self.x: train_set_x[batch_begin: batch_end]
            }
        )

它有效,但我无法传递corruption_level和learning_rate的值.

有人可以帮忙吗？谢谢! …
