I am trying to configure the “DL Keras Network Reader” node, but it tells me, that there is no available keras back end and that I should check my local installation.
I have pure python 2.7 and python 3.5 installed(not anaconda) and on both python there is keras installed. Funnily enough, when I use the “DL Python Network *” nodes I can use keras.
I try restart Knime after installation and have no result.
Any ideas, what I could to do fix this?
Just to double-check before we dive deeper into your problem: Did you check
https://knime.com/deeplearning for installation instructions?
@christian.dietz. Of course i check. In manual use conda, but i use pure python( pip install). May be i can get logs of node?
You can open the KNIME log via
View > Open KNIME log or open the log file. Can you copy paste the (relevant parts of) your log file here? Keras version etc are correct?
I reactivate this post because I think that I had the same error last Week.
I had Knime 3.6.1 installed and I could used Keras. Then I upgraded Knime to 3.7 (to try jupyter integration ;), and I obtained the same error message as in this post:
thanks for the info. i tried to take an old zipped version but Knime won’t allow me to install older versions of the plugins. i guess waiting will then be the only option, as i don’t want to do a complete re-installation.
btw the error massage I get is the following:
Traceback (most recent call last):
File “C:\Program Files\KNIME\plugins\org.knime.python2_3.6.0.v201807061638\py\PythonKernelBase.py”, line 278, in execute
exec(source_code, self._exec_env, self._exec_env)
Finally I re-installed Knime 3.6.2 and then I could used Keras without problem.
All this without modifing my python/keras installation.
Thus for me it seems that the corrected error in Knime 3.6.1-2 came back …
Could you check this?
Could you please upload your knime.log file? It can be found in your KNIME workspace directory under
.metadata/knime or, within KNIME Analytics Platform, via View > Open KNIME log.
Sorry but, as I uninstalled Knime 3.7 and re-installed the 3.6.2 version, the log file I have will not help you.
If necessary I can do the update once again to regenerate the error.
If it isn’t too much trouble, this would greatly help
. We’re currently not able to reproduce the problem on any of our machines.
I just did the update from Knime 3.6.2 to 3.7.1 and no problem… I cannot reproduce the problem I had.
The only difference is that the first time (when I obtained the error) I did the update starting from the 3.6.1 version.
Thanks for your help,
Thanks for double-checking! That’s (probably) good news for KNIME 3.7. We’ll have a look into how 3.6.1 and 3.6.2 differ with respect to their update processes to 3.7. It sounds rather odd that they result in different behaviors.
