Hi,
Gentle Reminder!
Could you please check this

[titu1994]

The error mentions to return a tensor, not a function. Can you check your return statement to make you return one or more tensors ?

[poojitharamachandra]

actually , the error is because of the function : _check_inputs

/usr/local/lib/python3.7/dist-packages/tfdiffeq/odeint.py:68 odeint *
tensor_input, func, y0, t = _check_inputs(func, y0, t)
/usr/local/lib/python3.7/dist-packages/tfdiffeq/misc.py:317 _check_inputs *
