使用 RASA NLU 训练模型时的 Tensorflow 错误

Question

I am using RASA NLU. While training the bot I am getting the following exceptionL

a. ImportError: No module named '_pywrap_tensorflow_internal'
b. Failed to load the native TensorFlow runtime.

and quite a bit of errors in stack trace as one can see at the end of the post.

Here is snippet of versions I am using for different modules with python 3.6.8 :

tensorboard                        1.8.0
rasa-core                          0.10.1
rasa-nlu                           0.13.0a2
Keras                              2.1.6

I ensured the training domain yaml is placed in right location and has no errors.

Answer 1

Seems like tensorflow is not correctly installed. Please try re-installing rasa-core with pip install -U rasa-core or even update to the new rasa package, which combines rasa-nlu and rasa-core (the old rasa-core and rasa-nlu are packages are deprecated). You can do so by doing pip install rasa .

Answer 2

为您解决这些 tensorflow 依赖项 - 请参见下文。

pip install rasa[convert]
