Risk index calculation error in report generation

[yihuicai]

I also met a similar issue when generating report, seems the numpy calculations return an object which is not compatible with DataFrame object in pandas library:

Traceback (most recent call last): File "/home/alan/simglucose/sim_origin.py", line 6, in <module> simulate(start_time=datetime.combine(datetime.now().date(), datetime.min.time()),controller=BBController(),cgm_seed=123412,animate=False,parallel=True) File "/home/alan/simglucose/simglucose/simulation/user_interface.py", line 383, in simulate results, ri_per_hour, zone_stats, figs, axes = report(df, save_path) File "/home/alan/simglucose/simglucose/analysis/report.py", line 251, in report ri_per_hour, ri_mean, fig_ri, ax5 = risk_index_trace(BG, visualize=False) File "/home/alan/simglucose/simglucose/analysis/report.py", line 102, in risk_index_trace fBG_df = pd.concat(fBG, axis=1).transpose() File "/home/alan/.local/lib/python3.10/site-packages/pandas/core/reshape/concat.py", line 372, in concat op = _Concatenator( File "/home/alan/.local/lib/python3.10/site-packages/pandas/core/reshape/concat.py", line 462, in __init__ raise TypeError(msg) TypeError: cannot concatenate object of type '<class 'numpy.float64'>'; only Series and DataFrame objs are valid

My dependencies are:

pandas: 2.0.2
numpy: 1.24.3
Python: 3.10.6
