张量流导入错误：_pywrap_tensorflow_internal.so：未定义符号：PyClass_Type

Question

我想做流媒体准确性并按照Tensorflow Audio recognition official webpage 上的说明进行操作。我的环境是virtualenv中的Ubuntu 16.04、Python 3.5、tensorflow 16.0。

在 virtualenv 环境中运行此命令后，

bazel run tensorflow/examples/speech_commands:generate_streaming_test_wav

出现了一些错误消息。详情请查看this gist。

简而言之，

第 1~7 行：我想确保导入 tensorflow 没问题

第 9~69 行：错误信息显示 Failed to load native TensorFlow runtime。

任何建议将不胜感激。谢谢。

关于最后一个错误： ImportError：无法导入张量流。不要从其源目录导入 tensorflow；

这意味着你不能在源代码路径的根目录中“导入 tensorflow”（如：/tensorflow-2.2.0）。您只需找到另一条路径，然后“导入 tensorflow”。

关于第一个错误，我想我遇到了类似的错误，我的解决方案是

1. pip 卸载 tensorflow
2. 重建张量流
3. 重新安装 tensorflow。
