Dimension does not match for tuple space

Suppose I have a observation space which is spaces.Tuple(spaces.Tuple([spaces.MultiDiscrete(), spaces.MultiDiscrete(), spaces.MultiDiscrete()]), spaces.Discrete(), spaces.MultiDiscrete()]).

And my observation_input is
observation_input = Input(shape=[3, 1, 1], name='observation_input')

Since my space is composed by 3 subspaces, and the first subspace is composed by three discrete subspaces.

Then I got the shape does not match error.

The shape obtained from state is (1, 1, 3), but required is [(None, 3, 1, 1)].

ValueError: Error when checking : expected flatten_1_input to have 4 dimensions, but got array with shape (1, 1, 3)

Any suggestions about this, thanks.
