我正在尝试使用 tensorflow 插件进行图像仿射转换，但我遇到了奇怪的错误。

我使用 anaconda 安装了 tensorflow 2.1，然后在 conda 上尚不可用的相同环境中安装 tensorflow 插件。错误可能来自那个事实......

这是代码，任何人都可以尝试吗？

some_image_path = '/path/to/an/image'
with open(some_image_path, 'rb') as f:
    image = tf.io.decode_image(f.read())

ops = tfa.image.transform_ops.angles_to_projective_transforms(90, image.shape[0], image.shape[1])
image = tfa.image.transform(image, ops)

这里的日志跟踪：

好的，抱歉，实际上是将 pip 包与 conda 混合使用的错误。

所以解决方案是使用 pip 而不是 conda，直到 tensorflow 插件在 conda 上发布！
