zip to hdf5 error #10

Closed Alexbeast-CN closed 2 years ago

Alexbeast-CN commented 2 years ago

I got the following error while tring to convert the .zip to .hdf5 using

python -m shift_dev.io.to_hdf5 "/home/tim/AD_models/SHIFT_Dataset/SHIFT/*.zip" -j 1

The error says:

Hey @Alexbeast-CN! I have tried but I could not reproduce this error on my side. The problem looks like a version compatibility issue with Numpy and Pycocotools. Did you have any issue when running import pycocotools._mask alone? If so, perhaps you need to install pycocotools manually. This post (https://github.com/cocodataset/cocoapi/issues/248) may be helpful.

Thank you for your reply. After reinstall pycocotools using the following command, it works!

pip install git+https://github.com/philferriere/cocoapi.git#subdirectory=PythonAPI
