Thank you for your post. We noticed you have not filled out the following field in the issue template. Could you update them if they are relevant in your case, or leave them as N/A? Thanks.
What is the top-level directory of the model you are using
Have I written custom code
Bazel version
CUDA/cuDNN version
GPU model and memory
Exact command to reproduce

Follow.. I have face the exactly same issue

[atercaelum]

I have the same issue. I'm running Visual Code.

Btw, @757227488 i ran into issue using python 3.7 and tensor flow. i read tensorflow is not supporting python 3.7

Here is my info:

• ### **OS Platform and Distribution ###
  win10
• TensorFlow installed from rasa_nlu[tensorflow]:
  * Anaconda3
• TensorFlow version ():
  1.13.0-rcl
• Python version ():
  3.6.8

i ran example from rasa after i already build a model:

from rasa_nlu.model import Metadata, Interpreter
import json
def pprint(o):
print(json.dumps(o, indent=2))
interpreter = Interpreter.load(/'./models/current/nlu/')
pprint(interpreter.parse(u"Hello"))

I might be missing a lib because it worked fine when i ran in the windows power shell.

after installing rasa_core i saw that it installed many other libs and uninstalled and installed tensorflow, it's current version is 1.13.1. i now don't have this error.

Same issue. Tried

conda update conda
conda update anaconda

mentioned in https://github.com/tensorflow/tensorflow/issues/25729#issuecomment-480657490
did not work.
I got this error after running

pip install -U tensorflow

Please let me know how to solve the issue.

I ran into the same issue. I don't think it is directly an issue with tf see In my case I had not changed anything in tf but installed some other packages which reinstalled amongst other things numpy. The following fixed the issue for me

pip uninstall numpy # Keep repeating till all version of numpy are uninstalled
pip install numpy

@mrevow Thank you! I was facing a similar problem while running TF based script for image processing. Re-installing the version of numpy solved it for me.

Windows 7 | Installed from Anaconda 3 | TF version: 1.13.1 | Python version: 3.6.3

Closing this issue since its resolved. Feel free to reopen if still have any further questions. Thanks !
