Error when resetting environment

[lcdbezerra]

Hi. I just cloned the repo and tried to run the example in the readme file.

env = gym.make("Foraging-8x8-2p-1f-v2")
env.reset()

But then I got an error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/camaral/miniconda3/envs/lbforaging/lib/python3.7/site-packages/gym/wrappers/order_enforcing.py", line 42, in reset

    row = self.np_random.randint(0, self.rows)
AttributeError: 'numpy.random._generator.Generator' object has no attribute 'randint'

This is probably related to the NumPy version, but it doesn't say anywhere which version to use

Dependencies:

python=3.7.13
gym=0.26.2
numpy=1.21.6
