I am running detectron2 in a docker file (clone from repository) and while running the demo.py I am getting the following error:

Traceback (most recent call last): File "demo.py", line 17, in from predictor import VisualizationDemo File "/home/appuser/detectron2_repo/demo/predictor.py", line 10, in from detectron2.engine.defaults import DefaultPredictor File "/home/appuser/.local/lib/python3.6/site-packages/detectron2/engine/init.py", line 12, in from .defaults import * File "/home/appuser/.local/lib/python3.6/site-packages/detectron2/engine/defaults.py", line 38, in from detectron2.modeling import build_model File "/home/appuser/.local/lib/python3.6/site-packages/detectron2/modeling/init.py", line 5, in from .backbone import ( File "/home/appuser/.local/lib/python3.6/site-packages/detectron2/modeling/backbone/init.py", line 15, in from .vit import ViT, SimpleFeaturePyramid, get_vit_lr_decay_rate File "/home/appuser/.local/lib/python3.6/site-packages/detectron2/modeling/backbone/vit.py", line 10, in from fairscale.nn.checkpoint import checkpoint_wrapper File "/home/appuser/.local/lib/python3.6/site-packages/fairscale/init.py", line 12, in from . import nn File "/home/appuser/.local/lib/python3.6/site-packages/fairscale/nn/init.py", line 9, in from .data_parallel import FullyShardedDataParallel, ShardedDataParallel File "/home/appuser/.local/lib/python3.6/site-packages/fairscale/nn/data_parallel/init.py", line 8, in from .fully_sharded_data_parallel import FullyShardedDataParallel, OffloadConfig, TrainingState, auto_wrap_bn File "/home/appuser/.local/lib/python3.6/site-packages/fairscale/nn/data_parallel/fully_sharded_data_parallel.py", line 43, in from fairscale.nn.misc import FlattenParamsWrapper File "/home/appuser/.local/lib/python3.6/site-packages/fairscale/nn/misc/init.py", line 12, in from .flatten_params_wrapper import FlattenParamsWrapper File "/home/appuser/.local/lib/python3.6/site-packages/fairscale/nn/misc/flatten_params_wrapper.py", line 34, in from fairscale.experimental.nn.ssd_offload import SsdFlatParameter File "/home/appuser/.local/lib/python3.6/site-packages/fairscale/experimental/nn/ssd_offload.py", line 6 from future import annotations ^ SyntaxError: future feature annotations is not defined

Should I upgrade python to 3.7 as currently it is running in 3.6.9 to fix this issue or any other fix?
