tensorflow lite 转换失败。“未定义符号：_ZTIN10tensorflow6DeviceE”发生

Question

tflite_model = converter.convert()
tflite_model_file = 'converted_model.tflite'

with open(tflite_model_file, "wb") as f:
  f.write(tflite_model)

当我最终在 dot convert 方法中转换模型时，出现了一些错误。

错误信息：

ValueError: Failed to parse the model: /tensorflow-2.1.0/python3.6/tensorflow_core/lite/python/optimize/_tensorflow_lite_wrap_calibration_wrapper.so: undefined symbol: _ZTIN10tensorflow6DeviceE.

即使通过我没有找到什么是

_ZTIN10tensorflow6DeviceE

如何转换迁移学习模型？

我遇到了同样的问题 - 安装夜间构建（当前为“2.1.0-dev20200104”）解决了它。

!pip3 uninstall tensorflow
!pip3 install tf-nightly
