When I run train.py(tags v5.0) in pycharm, I find this error Traceback (most recent call last): File "E:\Chrome download\yolov5-5.0\yolov5-5.0\train.py", line 21, in from torch.utils.tensorboard import SummaryWriter File "D:\Anaconda3\envs\pytorch\lib\site-packages\torch\utils\tensorboard__init.py", line 13, in from .writer import FileWriter, SummaryWriter # noqa: F401 File "D:\Anaconda3\envs\pytorch\lib\site-packages\torch\utils\tensorboard\writer.py", line 13, in from tensorboard.summary.writer.event_file_writer import EventFileWriter File "D:\Anaconda3\envs\pytorch\lib\site-packages\tensorboard\summary__init__.py", line 22, in from tensorboard.summary import v1 # noqa: F401 File "D:\Anaconda3\envs\pytorch\lib\site-packages\tensorboard\summary\v1.py", line 23, in from tensorboard.plugins.histogram import summary as _histogram_summary File "D:\Anaconda3\envs\pytorch\lib\site-packages\tensorboard\plugins\histogram\summary.py", line 35, in from tensorboard.plugins.histogram import summary_v2 File "D:\Anaconda3\envs\pytorch\lib\site-packages\tensorboard\plugins\histogram\summary_v2.py", line 35, in from tensorboard.util import tensor_util File "D:\Anaconda3\envs\pytorch\lib\site-packages\tensorboard\util\tensor_util.py", line 20, in from tensorboard.compat.tensorflow_stub import dtypes, compat, tensor_shape File "D:\Anaconda3\envs\pytorch\lib\site-packages\tensorboard\compat\tensorflow_stub\init.py", line 25, in from . import app # noqa File "D:\Anaconda3\envs\pytorch\lib\site-packages\tensorboard\compat\tensorflow_stub\app.py", line 21, in from . import flags File "D:\Anaconda3\envs\pytorch\lib\site-packages\tensorboard\compat\tensorflow_stub\flags.py", line 25, in from absl.flags import * # pylint: disable=wildcard-import File "D:\Anaconda3\envs\pytorch\lib\site-packages\absl\flags\init__.py", line 35, in from absl.flags import _argument_parser File "D:\Anaconda3\envs\pytorch\lib\site-packages\absl\flags_argument_parser.py", line 82, in class ArgumentParser(Generic[_T], metaclass=_ArgumentParserCache): TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases Can you help me to resolve it?

This is not an envpool-related issue. The traceback suggests it’s a PyTorch tensorboard issue. The suggestion I can give is to either upgrade tensorboard and PyTorch to the newest possible version, or open an issue in their GitHub repo.
