I just updated the pandas to 0.13.1 from the previous version - happily, this opened some options for me unfortunately From, it seems that some of my data tilt codes have caused problems. I did not make any changes other than updating the panda version from 0.11.0. The code that used to work first, and now works, is as follows: g_pres dropdown (0) And / or g_pres = (= 'follow', 'focal', 'std_epoch']) drop-duplicates (0) Error using any of the results: (Previous) --------------------------- -------------------- ---------------------------- Attribute error Tracebacks (most recent call final) & lt; Ipython-input-169-5d3c7458da40 & gt; In & lt; Module & gt; () ---- & gt; 1 g_pres = g_pres.groupby (['follow', 'focal', 'std_epoch']).

I am getting a strange error from Consumable when compiling the code should be the straight line of code. This code generates an error: size_t s = 5; Std :: vector & lt; Double & gt; Best Scords {0}, I'm just trying to use to fill a new vector with values ​​of five -1.0. The error I get is Non-continuous expression can not be compressed with type 'size_type' (aka 'unsigned long') to 'double' in the initial list. What's going on? It's compiled exactly: std :: vector & lt; Double & gt; Best Scores {5, -1.0}; Is she trying to use the initial list creator? I thought you should have two curl braces for it: std :: vector & lt; Double & gt; Best Scores {{5, -1.0}}; The issue is that you create a vector using a brace-attached initial list are doing. This applies to std :: initializer_list & lt; T & gt; Producer supports this condition, size_t , -1.0 list std :: initializer_list & lt; Do...
