module 'recsim_ng.core.value' has no attribute 'Space'

[aSeriousCoder]

Hi, I'm following your tutorials, but encounter with one trouble...

In "The User Model" part of second tutorial (RecSim_NG_Dealing_With_Uncertainty.ipynb), we need to do some imports, as belows:

from recsim_ng.stories import recommendation_simulation as simulation
from recsim_ng.applications.latent_variable_model_learning import recommender
from recsim_ng.entities.recommendation import user
from recsim_ng.entities.state_models import static
from recsim_ng.entities.choice_models import selectors
from recsim_ng.entities.choice_models import affinities

But the second import throw an error as belows:

AttributeError                            Traceback (most recent call last)
<ipython-input-5-d9a555230cf0> in <module>
      1 # @title RecSimNG modeling imports.
      2 from recsim_ng.stories import recommendation_simulation as simulation
----> 3 from recsim_ng.applications.latent_variable_model_learning import recommender
      4 from recsim_ng.entities.recommendation import user
      5 from recsim_ng.entities.state_models import static

     27 Value = value.Value
     28 ValueSpec = value.ValueSpec
---> 29 Space = value.Space
     30 
     31 

AttributeError: module 'recsim_ng.core.value' has no attribute 'Space'

And I checked the source code then and indeed, I can't find "Space" Class in recsim_ng.core.value

Looking forward to your kindly help.

Hi,

Thanks for using RecSim NG. As we can see the Space class was moved to field_spec.py already: https://github.com/google-research/recsim_ng/blob/master/recsim_ng/applications/latent_variable_model_learning/recommender.py#L31 At some point there was a discrepancy between GitHub and PIP package so please upgrade RecSim NG properly to fix this problem.

Thanks for your detailed response! I have fixed this according to your instructions.

Hope a new version of recsim_ng could land on PIP soon.

Still finding the same error, what do you mean by "upgrade RecSim NG properly"

try installing recsim_ng using pip install .
