Prerequisite

• [X] I have searched Issues and Discussions but cannot get the expected help.
• [X] The bug has not been fixed in the latest version (0.x) or latest version (1.x).

Task

I'm using the official example scripts/configs for the officially supported tasks/models/datasets.

Branch

main branch https://github.com/open-mmlab/mmocr

Environment

----system env---- CUDA: 12.3 System: Linux(Centos8) Python: 3.8 Pytorch: 2.1.2

Reproduces the problem - code sample

from mmocr.apis import MMOCRInferencer ocr = MMOCRInferencer(det='DBNet', rec='CRNN') ocr('demo/demo_text_ocr.jpg', show=True, print_result=True)

Reproduces the problem - command or script

1. 运行安装文档中的代码 git clone https://github.com/open-mmlab/mmocr.git cd mmocr pip install -v -e .
2. 安装openmim、mmengine、mmcv、mmdet pip install -U openmim mim install mmengine mim install mmcv mim install mmdet
3. 运行安装文档中的示例代码 from mmocr.apis import MMOCRInferencer ocr = MMOCRInferencer(det='DBNet', rec='CRNN') ocr('demo/demo_text_ocr.jpg', show=True, print_result=True)
4. 安装mmocr

Reproduces the problem - error message

根据安装文档安装得到的mm库版本： mmengine: 0.10.3 mmcv: 2.2.0 mmdet: 3.3.0 mmocr: 1.0.1 运行文档的示例代码会报错，提示mmdet版本与mmocr不兼容 MMDetection 3.3.0 is incompatible with MMOCR 1.0.1. Please use MMDetection >= 3.0.0rc5, < 3.2.0 instead. 于是卸载mmdet重新下载了3.0.0rc5版本 再次运行示例代码，提示mmcv版本被使用，但不兼容 MMCV==2.2.0 is used but incompatible. please install mmcv>=2.0.0rc4,<2.2.0. 卸载mmcv重新下载2.0.0rcx（x表示1/2/3/4任意版本）或2.0.1等版本会在命令行提示如下报错 note: This error originates from a subprocess, and is likely not a problem with pip. ERROR: Failed building wheel for mmcv Running setup.py clean for mmcv Failed to build mmcv ERROR: Could not build wheels for mmcv, which is required to install pyproject.toml-based projects ---mmcv 的下载--- try to install mmcv from source. https://mmcv.readthedocs.io/en/latest/get_started/build.html#build-mmcv 可以build但版本仍然是2.2.0，也会报错 MMCV==2.2.0 is used but incompatible. please install mmcv>=2.0.0rc4,<2.2.0.

Solved the same problems by specifying the version of mmcv during installation.

1. uninstall mmcv with code below in your virtual env for mmdetection: mim uninstall mmcv
2. to specify the version of mmcv, you can use the following command: mim install "mmcv==2.1.0" It's not necessary to use 2.1.0, but I just tried this one and it works for me

or maybe just change the maximum version as #11668 suggested Hope this could help! I guess OpenMMLab will fix it soon.

I specified the version of mmcv as you suggested, then I followed the suggestion in #11668. It works now, thank you!!!

Running the following command shows that mmcv 2.1.0 was installed but when I import it and check the version, it shows 2.2.0 (???) and the error persists.

mim install "mmcv==2.1.0"

I've been trying to install this tool for the last 4 hours and still stuck on this error. I've tried installing with pip, mim, and from source.
