[patrickphat]

Disclaimer: I'm a complete newbie on Docker, just want this thing to work :( After i run $ nvidia-docker build -t <name_or_tag> . I got this The command '/bin/sh -c egrep 'python-dateutil' python/requirements.txt > python/requirements.pip.txt && egrep -v 'python-dateutil' python/requirements.txt > python/requirements.conda.txt && conda install -y --file=python/requirements.conda.txt pip curl gflags glog leveldb libprotobuf libtiff libpng lmdb protobuf pydot scikit-image scipy snappy && pip install -r python/requirements.pip.txt' returned a non-zero code: 1
