[Bug] Unable to pretrain a model with dataset twice

See original GitHub issue

Describe the bug

ValueError: Variable pretrain/model/pi_fc0/w/Adam/ already exists , disallowed. Did you mean to set reuse=True or reuse=tf.AUTO_REUSE in VarScope? Originally defined at: File “/usr/local/lib/python3.6/dist-packages/stable_baselines/common/base_class.py”, line 266, in pretrain optim_op = optimizer.minimize(loss, var_list=self.params)

Code example

model.pretrain(dataset, n_epochs=10)
# some code that changes values in the dataset
model.pretrain(dataset, n_epochs=10)
