ImportError - Githubissues

My setting: cuda 10.2 python=3.8

intsall SparseBit by :

git clone https://github.com/megvii-research/Sparsebit.git
cd sparsebit
python3 setup.py develop --user
pip3 install tensorrt-8.2.5.1-cp38-none-linux_x86_64.whl

after installed that: run /root/Sparsebit/examples/cifar10_ptq/main.ipynb, but exposing RuntimeError: Ninja is required to load C++ extensions, so ,also run pip install Ninja, then run main.ipynb again, exposing an error:

Output exceeds the [size limit](command:workbench.action.openSettings?[). Open the full output data [in a text editor](command:workbench.action.openLargeOutput?9abbaedb-76bc-4b54-8e8c-3079840743b9)
