I using conda(miniconda)… I was crazy fast!!
Help me! ┭┮﹏┭┮


All your errors are related to environment set up. I think it might be useful to reset your environment completely, and make sure theano can be imported and run (e.g., follow http://deeplearning.net/software/theano/install_windows.html#requirements-installation-through-conda-recommended).

Python == 2.7* or ( >= 3.4 and < 3.6 )

I use Python 3.7…Am I gone???
Yet another, using miniconda’s instructions “conda install pymc3” cause error , like some “matplotlib”/“numpy”/“scipy” about Pymc3 will be WARNING

I use Pycharm install the Pymc3


When I uninstall “mingw-w64-install”/“tdm64-gcc-5.1.0-2”, the code is working
Just WARNING “no g++”/“no c++”…
What is your idea??

Help meφ(>ω<*) Our Dear junpeng…

This is a pretty weird error - again, keep the “mingw-w64-install”/“tdm64-gcc-5.1.0-2” installed, and try from a jupyter notebook first.

Python 3.7 can’t use theano???

@junpenglao Help,HElp,HELp,HELP. Dear junpeng

I reinstall miniconda and just “conda install pymc3”
Well… The warning is shown below:

Try: pm.sample(100, cores=1)

Dear junpeng…(>ω<*) The warning changed:
PS: Red arrow is “no g++”/“no c++”, using Python output
I found code can wrok when “no g++”/“no c++”, If “conda install pymc3”,code can’t work

I dont think there are any more g++ error.
So to recap:
The error you are seeing before is related to multi-processing in Windows, which we are currently tracking it here: https://github.com/pymc-devs/pymc3/issues/3140
The error you are seeing now is model related, the solution is a bit more complicated so you should start with simpler model and work your way up.

Dear junpeng
如果我不用theano相关的g++ c++,以及使用miniconda的"conda install pymc3" 来自动找到相关的库并安装,那么就会有g++,c++的警告,但是呢,能运行出结果
只要不论是自行安装tdm64-gcc、mingw-w64,还是使用miniconda的“conda install pymc3”。就一定会报错

但是你的意思似乎是说,现在的错误已经无关theno的g++ c++实现,而是win10有关的多核运行问题?我的理解对吗?

Yes - That’s why your code can run after setting cores=1.

You should have a look at the repo for the updated code - there are many changes since then the model might need improvement after its first published.
