Unknown parameter variable theano, can't get the package to work on Mac

[Leo]

I have some issues with theano package on my mac. I am getting the following error.

  

    File "/Users/model.py", line 355, in train

        train_model = theano.function(

    

      File "/Applications/anaconda3/lib/python3.8/site-packages/theano/compile/function/__init__.py", line 337, in function

      File "/Applications/anaconda3/lib/python3.8/site-packages/theano/compile/function/pfunc.py", line 426, in pfunc

        inputs = [

    

      File "/Applications/anaconda3/lib/python3.8/site-packages/theano/compile/function/pfunc.py", line 427, in <listcomp>

        _pfunc_param_to_in(p, allow_downcast=allow_input_downcast) for p in params

    

      File "/Applications/anaconda3/lib/python3.8/site-packages/theano/compile/function/pfunc.py", line 543, in _pfunc_param_to_in

        raise TypeError(f"Unknown parameter type: {type(param)}")

    

    TypeError: Unknown parameter type: <class 'theano.tensor.var.TensorVariable'>

I already tried setting this:

    theano.config.floatX = 'float64'

but didn't help unfortunately. 

I have the following versions of the packages.

python version 3.8.8

theano version 1.0.5

pymc3 version 3.11.1
