如何在AN中使用GPU时找到哪个变量是float64

Question

在no中，使用gpu时，变量必须是float32。我检查了我所有的变量都是folat32，但是我仍然得到下面的错误。在

ERROR (theano.gof.opt): Optimization failure due to: local_gpu_incsubtensor

似乎有些变量仍然是float64，我的问题是如何定位我使用float64变量的位置。在

对于no 0.7，可以使用no标志：warn_float64。你可以给他一个值：“忽略”、“警告”、“提升”、“pdb”。在

这使您可以轻松找到float64的创建位置。在
