```
# set parameters
params = params.params()
params.rmpc = rmpc
# get SIF embedding
embedding = SIF_embedding.SIF_embedding(We, x, w, params) 
```
an get this error
```
AttributeError: 'params' object has no attribute 'params'
```
and I verified the module params and its true, please help me how to deal with this?
