I'm having the same issue. Compiles fine, then gives the error when run via spark-submit. Nothing passed into spark-submit besides the jar file: spark-submit /path/to/jar/application.jar

I believe I tried that initially to no avail. There's no way for me to retest it at this point.

I looked in the app repo to see if there was already an issue there but not this repo obv so sorry if it's a dupe!

Changing line 893 in pyfolio/timeseries.py from: ``` valley = np.argmin(underwater) # end of the period ``` to: ``` valley = underwater.idxmin() # end of the period ``` appears to fix...
