I just dele the scala kerenl :
rm -rf ~/.local/share/jupyter/kernels/scala/

then reinstall it
curl -L -o coursier https://git.io/coursier-cli && chmod +x coursier SCALA_VERSION=2.12.10 ALMOND_VERSION=0.9.1 ./coursier bootstrap -r jitpack \ -i user -I user:sh.almond:scala-kernel-api_$SCALA_VERSION:$ALMOND_VERSION \ sh.almond:scala-kernel_$SCALA_VERSION:$ALMOND_VERSION \ --sources --default=true \ -o almond ./almond --install
that solve my problem ,everything is ok.sorry to disturb you`

becaue of Great firewall in China ,While I first installed the scala kernel , maybe something was missing .Second time , I set appropriate proxy, the installtion process was soon completed.
