from scipy.linalg import _fblas ImportError: DLL load failed: The specified module could not be found.

[Mike S]

I have Python 3.4.4 installed on Windows 7, also IPython, scipy, numpy,
statsmodels, and a lot of other modules, and am working through this
tutorial
http://www.analyticsvidhya.com/blog/2016/02/time-series-forecasting-codes-python/

In Ipython notebook I run this code

from statsmodels.tsa.stattools import adfuller
def test_stationarity(timeseries):
#determining rolling statistics
rolmean = pd.rolling_mean(timeseries, window=12)
rolstd = pd.rolling_std(timeseries, window=12)
#plot rolling statistics
orig = plt.plot(timeseries, color='blue', label='Original')
mean = plt.plot(rolmean, color='red', label='Rolling Mean')
std = plt.plot(rolstd, color='black', label='Rolling Std')
plt.legend(loc='best')
plt.title('Rolling Mean and Standard Deviation')
plt.show(block=false)
#perform Dickey=Fuller test
print('Results of Dickey-Fuller Test:')
dftest = adfuller(timeseries, autolag='AIC')
dfoutput = pd.Series(dftest[0:4], index=['Test
Statistic','p-value','#Lags Used','Number of Observations Used'])
for key, value in dftest[4].items():
dfoutput['Critical Value (%s)'%key]=value
print(dfoutput)
test_stationary(ts

And see this output:

Do I read this correctly to mean that the very last import statement is
the one having the problem,

"from scipy.linalg import _fblas"

How do I troubleshoot this? I'm wondering if I have version conflict
between two modules.

Thanks,
Mike

Alomost certainly, hopefully this link will help.

No problem :)

My fellow Pythonistas, ask not what our language can do for you, ask
what you can do for our language.

Mark,

I uninstalled scipy, numpy and pandas, then installed this version
scipy-0.15.1-win32-superpack-python3.4
I had previously installed this version
scipy-0.16.1-win32-superpack-python3.4
That solved the conflict, you have great search skills, I tried but
didn't find a resolution.

Thanks Very Much!
Mike
