And also, I received the link to the page of installing mmdet on colab from one of you earlier in another issue I posted. This is the address as I opened the page on colab (https://github.com/openmmlab/mmdetection/blob/master/demo/mmdet_inference_colab.ipynb) However, when I rechecked the page after the error occurred, it was gone.
same problem.
Hi @ahchang2 You may try to install mmcv==0.6.2.

@ShidiDaisy There basically are two workarounds.
pip install mmcv-full
or install pre-build ones from here. @ShidiDaisy There basically are two workarounds.
- Install latest mmdet and
pip install mmcv-full
or install pre-build ones from here.- Install mmcv==0.6.2 and mmdet==2.2.1
But I still hit this error after I pip install mmcv-full
.

I also tried 'python setup.py develop',but still can't get rid of the error.

I was getting ModuleNotFoundError: No module named 'mmcv.ops', so I tried installing mmcv==0.6.2 and mmdet==2.2.1, but then I got the error, ERROR: No matching distribution found for mmdet==2.2.1. The training was working when I installed mmcv-full however I was having the same issue as #3259, so I'm currently following the Author of the issue #3259, solution. Any help would be appreciated.
Same error. Oh my god.
This works 100%.

Hi @ShidiDaisy
Please first uninstall any previous version of mmcv.
And run pip install mmcv-full
.
Please refer to install guide for details.
@xvjiarui Following latest install guide and cloned lastest master branch code. I receive the error: ModuleNotFoundError: No module named 'mmcv._ext'
Hi @peeyushpashine
You need to install mmcv-full.
You may run pip install mmcv-full
.
@xvjiarui Yes, still the same issue.
Hi @ShidiDaisy Please first uninstall any previous version of mmcv. And run

But I got this issue:

after I
pip uninstall mmcv, pip install mmcv-full
Hi @peeyushpashine , @ShidiDaisy ,
You may need to use pip uninstall mmcv
multiple times to ensure that there is no old mmcv in the python site-packages first. Some times the mmcv might not be totally wiped out for some reasons.
Then you can install mmcv-full using pip install mmcv-full
. Please ensure that this time mmcv is successfully compiled and installed.
I did a fresh build with a new environment, and everything works as expected.
Hi @peeyushpashine You need to install mmcv-full. You may run
pip install mmcv-full
.
useless
Perhaps it's a path related issue? The following command worked:
python -m pip install mmcv==0.6.2
Somehow in the latest master code i do not see issue anymore.
Here is the complete solution by setting all requirements:
from IPython.display import clear_output
os.environ['PYTHONPATH'] = "/usr/bin/python3"
!wget https://repo.continuum.io/miniconda/Miniconda3-4.5.4-Linux-x86_64.sh && bash Miniconda3-4.5.4-Linux-x86_64.sh -bfp /usr/local

If you installed mmcv-full
, you should not install mmcv
. You can try to not install mmcv and see if it works.
I run the MMCV_WITH_OPS=1 pip install -e . and then solve the problem just wait when running setup.py develop for mmcv-full
pip uninstall mmcv pip install mmcv-full
I fixed by pip install mmcv-full==1.0.5 It may depend on version?
first: pip uninstall mmcv then: pip install mmcv-full==latest+torch1.5.0+cu101 -f https://download.openmmlab.com/mmcv/dist/index.html my mmdet version is 2.4.0, mmcv>=1.1.0
If you have installed the correct version of cfg,remember use 'conda active mmdet'. It works
Can you please add mmcv-full as a dependency here in mmdet? Also just ran into this error. Also why does this need 10 minutes to install? Oo
First uninstall MMCV and MMCV-Full pip uninstall mmcv mmcv-full
Install MMCV from source. git clone https://github.com/open-mmlab/mmcv.git cd mmcv MMCV_WITH_OPS=1 python3 -m pip install -e . Note: Make sure that you are installing in respected Python and pip.
Install your mmcv-full correctly by pip install the according wheel version with your configuration in here. Scroll down for latest update
Thanks for the reply, resolved the issue installing it from sources.
Thanks and Regards, Surendra Allam.

Using google colab (march 2021) succesfully installed using:
%%bash
pip install torch==1.7.0
pip install mmdet==2.4.0
pip uninstall mmcv
pip install mmcv-full==latest+torch1.7.0+cu110 -f https://download.openmmlab.com/mmcv/dist/index.html

It works well for me. Thanks!

For example mine is 11.0
Then download correct pytorch:
pip install torch==1.8.0+cu111 torchvision==0.9.0+cu111 torchaudio==0.8.0 -f https://download.pytorch.org/whl/torch_stable.html
This is Pytorch 1.8.0 with cuda 11.1.
Install correct mmcv as they mention in their README
pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/cu111/torch1.8.0/index.html
/cu111/torch1.8.0/
see how cuda and torch versions are matching
It should work 😃

I did it using pip. First, uninstall the previous version and then install 1.2.4.
Yes, I tried the installation after uninstalling the prior version. Doesn't work. Also, the pip install command doesn't work for me with any version. It always throws an error that ends with:

I am facing the same issue.

Which version of mmcv-full are you using??
I am using the latest clone. It is v1.3.0
Switch to version 1.2.4. It worked for me
Just gave it a try. It throws the same error. Did you install it using the repository or using the command:
pip install mmcv-full==1.2.4
I did it using pip. First, uninstall the previous version and then install 1.2.4.

did you solve it ?
Install from the sources worked for me, follow below steps.
For people still struggling with this error:
ModuleNotFoundError: No module named 'mmcv._ext'
1. It's important that pytorch - cuda - mmcv are compatible 2. Therefore first you should check your cuda version `nvidia-smi`
+-----------------------------------------------------------------------------+ | NVIDIA-SMI 450.102.04 Driver Version: 450.102.04 CUDA Version: 11.0 | |-------------------------------+----------------------+----------------------+
For example mine is
11.0
1. Then download correct pytorch:
pip install torch==1.8.0+cu111 torchvision==0.9.0+cu111 torchaudio==0.8.0 -f https://download.pytorch.org/whl/torch_stable.html
This is Pytorch 1.8.0 with cuda 11.1.
1. Install correct mmcv as they mention in their [README](https://github.com/open-mmlab/mmdetection/blob/master/docs/get_started.md)
pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/cu111/torch1.8.0/index.html
/cu111/torch1.8.0/
see how cuda and torch versions are matching1. It should work smiley

PS Here's our project where we used
mmdet
i have cuda 11.0 and tried your solution and got f'MMCV=={mmcv.__version__} is used but incompatible. ' \ AssertionError: MMCV==1.3.1 is used but incompatible. Please install mmcv>=1.2.4, <=1.3.
I run the MMCV_WITH_OPS=1 pip install -e . and then solve the problem just wait when running setup.py develop for mmcv-full
How do you run MMCV_WITH_OPS=1 pip install -e . I can not run it
I run the MMCV_WITH_OPS=1 pip install -e . and then solve the problem just wait when running setup.py develop for mmcv-full
How do you run MMCV_WITH_OPS=1 pip install -e . I can not run it
MMCV_WITH_OPS=1 pip install -e .
What I found useful was to first install mmcv
pip install mmcv
then run the collect_env.py script
$ python mmdet/utils/collect_env.py

After that just copy the cuda, and torch versions.
Then uninstall mmcv and then install mmcv-full
like so
pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/cu{cuda_version}/torch{pytroch version}/index.html
For me it was:
pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/cu102/torch1.8.1/index.html
If you have multiple cuda versions installed, then you need to select the cuda version that pytorch was built with - it said 10.2 for me, so I had to export CUDA_HOME=/usr/local/cuda-10.2
before the pip install command and it worked.
had the same issue.
Uninstalled the mmcv, installed mmcv-full==1.3.0 and it starts working
OK Thanks

Someone has already post this issue earlier, and I just wanna say I got the same issue. I'm using mmedetection on colab. I installed the program as usual, but when I tried to import inference_detector from mmdet.apis, I got the error as described in the title which I've never met before. I thought it may because some updates on your side were on progress, but I wasn't sure. Any suggestion? Thank you.
