Tensorflow build from Dockerfile.customtensorflow

ERROR:COPY failed: stat /var/lib/docker/tmp/docker-builder398654218/my-tensorflow-modifications.patch: no such file or directory

I pulled tensorflow image from NGC and copied Dockerfile.customtensorflow into my ubuntu system and ran command
docker build -t tensorflow_custom1 -f Dockerfile.customtensorflow

I’m in need of libtriton_tensorflow1.so as Im trying to build triton inference server from source. Please help.
