问题描述:
../anaconda2/lib/python2.7/site-packages/sklearn/externals/joblib/_multiprocessing_helpers.py:38: UserWarning: [Errno 13] Permission denied. joblib will operate in serial mode warnings.warn('%s. joblib will operate in serial mode' % (e,)) Segmentation fault
没错,发生了段错误,使用gdb 跟踪信息,也没找到,也就是无法使用多进程,只能串行.
解决方案:
ls -ld /dev/shm sudo chmod 777 /dev/shm
