输入错误：_pywrap_tensorflow_internal.so:未定义符号: PyClass_Type

Question

我想做流的准确性，并遵循Tensorflow音频识别官方网页上的说明。我的环境是virtualenv中的Ubuntu16.04、Python3.5、tensorflow 16.0。

在虚拟环境中运行此命令之后，

bazel run tensorflow/examples/speech_commands:generate_streaming_test_wav

出现了一些错误信息。有关更多细节，请查看这个要旨。

总之，

第1~7行:我想确保导入tensorflow是可以的

第9~69行:错误消息显示加载本机TensorFlow运行时失败。

任何建议都将不胜感激。谢谢。

关于最后一个错误: ImportError:无法导入tensorflow。不要从源目录导入tensorflow；

这意味着您不能在源代码路径的根中“导入tensorflow”(比如:/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，我想我遇到了一个类似的错误，我的解决方案是

1. pip卸载tensorflow
2. 重建丹瑟尔流
3. 重新安装tensorflow。
