Why I can not import from torch_geometric.graphgym.optimizer import create_optimizer, \ # create_scheduler, OptimizerConfig, SchedulerConfig

[123carmen]

I want to use windows , pycharm to run your code, [If i use linux system, it has no problem at all]
I installed torch_geometric in window pc

--I can successfully import those packages from a console,(torch1.10.0, )
import torch
import torch_geometric 2.0.4
import torch_scatter 2.0.9
import torch_sparse 0.6.13
import torch_spline_conv 1.2.1
import torch_cluster 1.6.0

but this line
from torch_geometric.graphgym.optimizer import create_optimizer,
create_scheduler, OptimizerConfig, SchedulerConfig
it shows errors on .graphgym.optimizer (as unrecognized modules).
I can not import from torch_geometric.graphgym.optimizer import create_optimizer,
create_scheduler, OptimizerConfig, SchedulerConfig --- from console, it can not import

error--- module = self._system_import(name, *args, **kwargs)
ModuleNotFoundError: No module named 'torch_geometric.graphgym.optimizer'

why linux system, it can import, and my window can not?

i try to replace from torch_geometric.graphgym.optimizer import
to from torch_geometric.graphgym.optim import ...

then when it goes to

optimizer = create_optimizer(model.parameters(),
new_optimizer_config(cfg))
it show errors, raise ValueError(f"'cfg.{arg_name}' undefined")
raise ValueError(f"'cfg.{arg_name}' undefined")
ValueError: 'cfg.optimizer_config' undefined

how can i solve this problem, thank you very much.

no problem now, I decrease the torch_geometric version. it is ok now. sorry to bother
