ModuleNotFoundError: No module named 'pycocotools.ytvos'

[CuberrChen]

hi！I successfully executed the instructions include in “Install pycocotools” part，but when I perform inference, the above problem occurs. I tried to solve it, but it didn't work. I hope to get your help！

hi @CuberrChen, you also need to install the ytvos version pycocotools, as mentioned in README.

[CuberrChen]

from pycocotools.ytvos import YTVOS from pycocotools.ytvoseval import YTVOSeval import datasets.transforms as T from pycocotools import mask as coco_mask

There is an error in the first two sentences, but there is no problem in the last sentence.

[Epiphqny]

@CuberrChen That is because you only installed coco version of pycocotools, as mentioned in README, you need to install both the coco and ytvos version of pycocotools.

[CuberrChen]

I think so too, but I have successfully implemented the installation instructions in README.md. emm..I'll try again. thanks！

@CuberrChen If there is still problem, you could try to directly copy the built pycocotools of ytvos to your python installation path.

It seems like the youtubevos cocoapi does not get properly set up for some people.
I actually found a way to solve this problem according to @Epiphqny 's comment and I'll write the details here.
I just copied the ytvos.py and ytvoseval.py files (you can find them here) to the right directory in the Python site-packages. For example, if you are using a conda environment named visTR and python 3.7, the directory to copy into will be something like ./anaconda3/envs/visTR/lib/python3.7/site-packages/pycocotools.

Don't use pip install pycocotools. please install pycocotools locally .https://github.com/youtubevos/cocoapi

This doesn't work.

I tried this method and successfully solved the error, great!Thanks bro！
