I have some code that imports theano. A bare exception is raised in the import of theano. SymPy's `import_module()` propagated the error instead catching it and returning `False`. Not quite sure why, …

Hi, thanks for making this lovely package.
I have a simple ODE model with the following code:
```python
import tensorflow as tf
import matplotlib.pyplot as plt
from tfdiffeq import odeint

Now cvode seems to be a reliable solver for stiff problems, but we still run into numerical issues from time to time (well we do go complex, but still).
I am just wondering if we are sqeezing every…

I played with Enzyme a little bit, and I suspect it's not ready for use with our package. It can't differentiate simple ODEs at present. There's a fair amount of linear algebra in OrdinaryDiffEq, so i…

This is in essence the same problem as https://github.com/SciML/OrdinaryDiffEq.jl/issues/2045, except that differential variables are present but evolve far too slowly to provide indirect error contro…

When you solve an ODE (pointwise) using the FEM the variable on the lhs is multiplied by the mass matrix upon discretisation. If you wrap the rhs in `pybamm.source` then it also gets multiplied by the…

When I run
```
ode23s(...)
```
on a linear ODE with ill-conditioned coefficient matrix, the estimated error `err` in line 302 returns `NaN`.
This results in being stuck in an infinite loop, since …

It might be useful to switch between stochastic and deterministic simulation based on the time step and molecule counts of each reaction. For example, stochastic complexation is currently finding the …

I'm trying to port some code from pure python to JAX. The code is a bit complicated with time-varying interpolated inputs but essentially involves solving a system of 8 coupled ODEs. The state variabl…
