【问题描述】：
我有一个可以在我的桌面上正常运行的 python 脚本。当我尝试在我的树莓派上运行它时，我遇到了一个错误。
要在树莓派上为 python 3.5 安装 tensorflow，我遵循了本教程：https://petewarden.com/2017/08/20/cross-compiling-tensorflow-for-the-raspberry-pi/ 没有适用于 tensorflow 和 python 3.5 的官方二进制文件，当我尝试自己编译时出现错误。本教程建议仅从 Python 3.4 二进制文件安装 tensorflow。
如果您运行的是 Python 3.5，则可以使用 Python 3.4 轮，但需要使用 对文件名稍作更改，因为它对版本进行了编码。你 每次导入 tensorflow 时都会看到一些警告，但它 应该可以正常工作。
这是我遇到的错误：

第 93 行尝试创建一个导致错误的 Estimator。
tf.contrib.learn.Estimator(model_fn=convolutional_neural_network, model_dir="tmp")
我在 github 上发现了类似的错误，但没有任何帮助：https://github.com/tensorflow/serving/issues/684
【问题讨论】：
-
错误信息表示库版本不匹配。所以，教程可能不对。可以试试 Python 3.4 吗？
-
我用 Python 2.7 尝试过，遇到了同样的错误。在此之前我做了一个全新的操作系统安装。 gist.github.com/anonymous/b18204febd4c06d456681e913cceeb9c
