还有偶尔报的.

1. 训练好模型

2. bigflow add 到bigflow 环境中

3. 调用pythonswig 接口预估

        cmd = "chmod +x ./fake/python27-gcc482/bin/python && \
                ./fake/python27-gcc482/bin/python \
                fake/conf/predict.py -n \
                fake/conf/trainer_config.py -w \
                fake/model/pass-000%s -b \
                fake/data/labels.list -d \
                fake/data/dict.txt" % tradeid
        pc = pc_tmp.map(lambda x: x) \

我搜了一下这个错误，看到这里facebook/rocksdb#606

这个错误是没有链接 -lrt造成的，你用ldd命令先看看依赖
