import ts raises ModuleNotFoundError: No module named 'symengine' about timesynth

Happy that that's working for you. Jenkins seems to work fine for both python 3.5 and 3.7 with this setup, so I might leave it this way for now.

Same issue here, using Python 3.7..

[1Reinier]

I’ll take a look

I had the same issue, but just needed to upgrade cython. Symengine was failing to build. Hope that helps.

He capaulson, can you elaborate what you did? I upgraded Cython but still does not work..

Replicated this issue on Travis for Python 3.7. Will fix soon.

[1Reinier]

should work now

[vincent-smit]

Thanks Reinier but.. tried with a fresh virtualenv but now I am getting the following error: ModuleNotFoundError: No module named 'jitcdde'..

[vincent-smit]

@1Reinier Got it working by running pip install jitcdde==0.32

Hi, I've got the same problem as Subrata.

Any idea how I can fix this? I've got python 3.8.1 and symengine 0.4 installed.

Sorry for the comment :) I did everything again in a conda environment and it worked.

Is there anything about symengine>0.4 that breaks TimeSynth? Because ==0.4.0 is keeping you in 3.7.

[CubeBot888]

For TimeSynth use with Python 3.8, perhaps implement the change in setup.py as per this unmerged pull request: https://github.com/TimeSynth/TimeSynth/pull/20/files
Or do: pip install --upgrade symengine==0.6.1
