AttributeError: 'RealDouble' object has no attribute 'real_part' about jitcdde HOT 2 CLOSED

Your problem is that you lack CMake, which is required to build the old version of SymEngine. You can probably solve this by installing CMake. Alternatively, you can install JiTC*DE fresh from the Git repository, where this was already fixed:

pip3 install \
        git+git://github.com/neurophysik/jitcxde_common \
        git+git://github.com/neurophysik/jitcode \
        git+git://github.com/neurophysik/jitcdde \
        git+git://github.com/neurophysik/jitcsde \
        --no-dependencies --user

It appears that I have to make a new release to deal with this issue.

Thank you for your support, Now it is working fine. The only warning that appears is from running the file two_Roesslers.py which is following

two_Roesslers.py:27: FutureWarning: arrays to stack must be passed as a "sequence" type such as list or tuple. Support for non-sequence iterables such as generators is deprecated as of NumPy 1.16 and will raise an error in the future.
data = np.vstack(DDE.integrate(T) for T in times)

Thank you once again.
