我在 pymc3 和 theano 上运行贝叶斯层次模型。当我开始训练我的模型时，我收到了这个错误：

有人可以帮我调试吗？一位同事尝试在他的机器上运行它并且它有效，所以我猜它与我的机器或可能与 theano 或 pymc3 的版本有关。
或者也许它与形状参数有关，但我再次怀疑，因为它已经在我同事的机器上工作了。我也尝试运行以下命令，但我不确定它的作用，我担心它只是隐藏了警告和重要消息
theano.config.gcc.cxxflags = "-Wno-c++11-narrowing"
最后，对于贝叶斯程序员（也许它可以帮助）非中心 Cholesky 重新参数化工作和编译没有错误。请帮我
谢谢
