Theano张量导入错误

Question

我一直在尝试在我的代码中导入 theano.tensor。我以前用过theano.tensor。我之前导入 theano.tensor 的所有代码在我的机器上都能完美运行。现在我正在尝试编写另一个从 theano 导入张量的脚本，但出现以下异常。

Traceback (most recent call last):

    OPT_NONE = gof.Query(include=[], exclude=exclude)
AttributeError: module 'theano.gof' has no attribute 'Query'

我找不到此异常的任何合理原因。

我想我明白你的问题了。在错误日志中查看：

File "/anaconda3/lib/python3.5/pdb.py", line 75, in <module>
    import code

我相信 Theano 中还有另一个名为 code.py 的脚本，当 python 解释器执行您的脚本时，它会从 pdb.py 调用，该脚本也被命名为 code.py.我猜 python 解释器混淆了这两个脚本并执行了错误的脚本！您可以更改文件名并检查错误是否消失。
