tensorrt不支持：tf.unpack，tf.slice，tf.tile，tf.expand_dims，tf.fill，tf.cast，tf.floor_div，tf.range

Question

从tensorflow模型转换为uff模型（例如tf.unpack, tf.slice, tf.tile, tf.expand_dims, tf.fill, tf.cast, tf.floor_div, tf.range）时，tensorrt有很多不受支持的操作。有没有简单的方法可以解决问题？ 当我将pb转换为uff模型时，这是警告：

您可以尝试使用TF-TRT，该方法只允许转换TRT支持的部分图形，而其余部分保留在TF中。您可以在此处找到一些示例：https://github.com/tensorflow/tensorrt
