PyCharm debugging no interaction

[peroveh]

I am testing diffeqpy in windows, running python 3.7 and PyCharm2020 together with julia 1.5.3 The simple demo code for a 1 order ode runs correctly ,,, but when single-stepping through the python code normal iteraction in the debug window is not possible. For example creating a new variable te=np.arange(0.,1,0.01) for computing a ode solution on a denser grid. At the breakpoint in the debugger, typing the above command takes a long time and returns nothing.. Even inspecting variables already executed in the code, yields nothing.. Is there any way of getting back the normal debugger behaviour in PyCharm when using diffeqpy as julia interface?
