我正在尝试使用 python 安装 GDAL。但它失败并出现错误。
我使用的命令是pip install GDAL.

if np.max(subgrid) == np.min(subgrid):
middle_middle = cur_subgrid + 1
else:
middle_middle = cur_subgrid
由于条件只能在运行时确定，我使用 Keras 语法如下
middle_middle = K.switch(K.max(subgrid) == K.min(subgrid), lambda: tf.add(cur_subgrid,1), lambda: cur_subgrid)
但我收到此错误：
