TypeError：輸入類型不支持ufunc'invert'，

Question

我已經用tensorflow克隆了U-net的存儲庫。

 labels = np.zeros((ny, nx, self.n_class), dtype=np.float32) 
     labels[..., 1] = label 
     labels[..., 0] = ~label 

我在3號線得到一個錯誤說：

類型錯誤：ufunc「倒置」不支持輸入類型，並輸入無法安全地強制轉換成任何支持的類型根據鑄造規則''安全''

我該如何調試？

聽起來像這可能是相同的問題，可以在Theano問題跟蹤器here中找到。

The error comes from numpy and is from the fact that you are mixing symbolic (Theano) and numeric (scipy) code. This will not work.

If you want to use a scipy function in theano you have to wrap it up as an op (maybe with @as_op http://deeplearning.net/software/theano/library/compile/ops.html#theano.compile.ops.as_op).
