Can't import scipy.stats

[Joe Prendergast]

Hello,

I'm running Spyder Python 3.3.6 from Stata/IC 16.1 for Mac (64-bit Intel):

. python query
------------------------------------------------------------------------------------------------------
Python Settings
set python_exec /users/jprenderg/opt/anaconda3/bin/python
set python_userpath

Python system information
initialized yes
version 3.7.4
architecture 64-bit
library path /Users/jprenderg/opt/anaconda3/lib/libpython3.7m.dylib

I can import scipy just fine. But when I try "from scipy import stats" I get the following error:

Traceback (most recent call last):
File "/users/jprenderg/desktop/python/pyex2.py", line 8, in <module>

Has anyone else experienced this or does anyone know a solution?

Thanks,

The following works under Windows:

python:
import os 
os.environ['QT_QPA_PLATFORM_PLUGIN_PATH'] = "C:/Users/scott/Anaconda3/Library/plugins"
import matplotlib.pyplot as plt
from scipy import stats
gaussian = stats.norm(loc=10.0, scale=1.0)
plt.hist(gaussian.rvs(10000), bins=50)
plt.show()
end

Perhaps this will help:

Hi Scott:

This runs fine:

import os
os.environ['QT_QPA_PLATFORM_PLUGIN_PATH'] = "/Users/jprenderg/Anaconda3/plugins"
import matplotlib.pyplot as plt

But "from scipy import stats" still produces the same error.

By the way, how do you get your code to appear in that well-formatted gray block?

Thanks.

You might try Stata tech support.

If you click on the "Underlined A" it will toggle the Advanced Editor and then the "#" button will wrap [CODE] tags around selected text
