On PyStan 2.18 /Windows
Errors
When I installed Python 3.7.1 and PyStan2.18, various errors on PyStan 2.18 occurred.
Hence, I reinstalled Python 3.6.6 and PyStan 2.17. Then, I can use PyStan as before (2018.10.28).
Python 3.6.6 was installed from the website
https://www.python.org/downloads/release/python-366/
I chose the file enclosed by the red frame in Figure 1

PyStan 2.17 was installed by this pip command
pip install pystan==2.17
The version of PyStan
is specified by “==2.17”.
