mmcv._ext error

Open timucinbulmus opened this issue 1 year ago • 8 comments

I have been working on setting environment with previous version of mmcv and I always get the same error. I have tried different version of pytorch, cuda and more however i couldnt solve the problem. Below, you can find error output and all the packages with the versions.

I found that just using pip to install all of the packages was what I needed. No need to use mim. This is what I ran in my docker file

RUN pip install openmim
RUN mim install "mmcv>=2.0.0"
RUN pip install "mmsegmentation>=1.0.0"

and then just make sure you initialize all of your modules properly in the init.py files and what not

@timucinbulmus Hi mate, have you solved the problem? Ive encountered the same issues even though trying different of versions using pip install or mim install whatever.

@timucinbulmus Hi mate, have you solved the problem? Ive encountered the same issues even though trying different of versions using pip install or mim install whatever.

Hi, I have not solved it and don't understand why it happens. I will give the solution as soon as I figured it out.

Hi,

Any body have solution for mmcv._ext error..

I have been using previous mmvc version like 1.2.4 version for some specific github codes. Swin_Transformer_Segmentation but those are supoored by previous mmcv version like 1.24 ,

But those ones asks for mmcv.ext error which is related with later solutions i guess.

I coul not have a solution for this error.

Any help appreciated.

I am also having the same problem. I have also tried using pip install mmcv-full like the past resolved issue suggested. However, mmcv-full is no longer suppoted.

I have found the answer. I reverted my PyTorch back to 2.1.2 and it solved the problem. Seems like torch 2.2.x and above is only supported by mmcv==2.2.0 (which is not supported to run mmseg yet)

Give this installation guide a shot. I install mine using pip.

For my case, I have been using a previous version which supports and implementation of segmentation with mmseg, with mmcv==1.2.5 version but in this case I get mmcv._ext error , I need support for this issue for previous versions ,

I have tried to run old version however i couldnt fix the issue. Therefore, i installed the later version. Below, you can find the libraries (in .yaml extension) i have now and it works for me.
