我正在使用PyMC3和joblib模块并行地将相同的multiprocessing模型拟合到不同的数据集，但遇到一个奇怪的错误。
尽管该模型适合绝大多数数据集，但对于随机子集却失败了，这是错误消息：

The above exception was the direct cause of the following exception:

No module named 'tmpttugnbtl'到底是什么意思：S？
我正在使用PyMC3的3.7版和Theano的1.0.4版。使用以下几行代码对代码进行了Parallellized
from joblib import Parallel, delayed
import multiprocessing
n_jobs = 32
result = Parallel(n_jobs)(delayed(fit_event)(directory) for directory in dirs)
