ModuleNotFoundError: No module named 'mmcv._ext' (Installation Issues)

[ab1412]

作者你好，我在复现您提供的github代码时出现了以下的报错，似乎和mmcv-full有关，我是通过pip install mmcv-full==1.3.0 -f https://download.openmmlab.com/mmcv/dist/cu111/torch1.9.0/index.html以及pip install mmcv-full==1.3.0都尝试过，但都是这个报错。请问有什么解决方法吗，以下是报错信息： (NVDS) qjc@omnisky:/data3/qjcnerf/NVDS$ CUDA_VISIBLE_DEVICES=0 python infer_NVDS_dpt_bi.py --base_dir ./demo_outputs/dpt_init/000423/ --vnum 000423 --infer_w 896 --infer_h 384 Traceback (most recent call last): File "infer_NVDS_dpt_bi.py", line 19, in from backbone import * File "/data3/qjcnerf/NVDS/backbone.py", line 15, in from mmseg.models.builder import BACKBONES File "/data1/qjc_new/anaconda/envs/NVDS/lib/python3.8/site-packages/mmseg/models/init.py", line 1, in from .backbones import * # noqa: F401,F403 File "/data1/qjc_new/anaconda/envs/NVDS/lib/python3.8/site-packages/mmseg/models/backbones/init.py", line 2, in from .fast_scnn import FastSCNN File "/data1/qjc_new/anaconda/envs/NVDS/lib/python3.8/site-packages/mmseg/models/backbones/fast_scnn.py", line 7, in from mmseg.models.decode_heads.psp_head import PPM File "/data1/qjc_new/anaconda/envs/NVDS/lib/python3.8/site-packages/mmseg/models/decode_heads/init.py", line 16, in from .point_head import PointHead File "/data1/qjc_new/anaconda/envs/NVDS/lib/python3.8/site-packages/mmseg/models/decode_heads/point_head.py", line 6, in from mmcv.ops import point_sample File "/data1/qjc_new/anaconda/envs/NVDS/lib/python3.8/site-packages/mmcv/ops/init.py", line 1, in from .bbox import bbox_overlaps File "/data1/qjc_new/anaconda/envs/NVDS/lib/python3.8/site-packages/mmcv/ops/bbox.py", line 3, in ext_module = ext_loader.load_ext('_ext', ['bbox_overlaps']) File "/data1/qjc_new/anaconda/envs/NVDS/lib/python3.8/site-packages/mmcv/utils/ext_loader.py", line 11, in load_ext ext = importlib.import_module('mmcv.' + name) File "/data1/qjc_new/anaconda/envs/NVDS/lib/python3.8/importlib/init.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) ModuleNotFoundError: No module named 'mmcv._ext' 以下是我的环境信息： `(NVDS) qjc@omnisky:/data3/qjcnerf/NVDS$ conda list packages in environment at /data1/qjc_new/anaconda/envs/NVDS:
