Can you provide more details:
- what platform / Python version?
- what PyStan version?
- provide a csv for your dataframe or describe the data.
- does another csv file (e.g. the example we provide) display the same issue?

Hi Sean, I am having the same issue although I am on Mac (El Capitan 10.11.4)
I am using:
- Anaconda 3 / python3.5
- pystan (2.14.0.0)
This happens both with my own data and also with all of the test examples provided.
My test data is pretty simple and has a simple data column and an integer:
y ds
0 5 2015-08-01
1 7 2015-08-02
2 11 2015-08-03
3 10 2015-08-04
4 10 2015-08-05
I also tried downgrading pystan to 2.12.0.0 but I still get the same error.

Ok, an update. I was very (stupidly) not looking at the jupyter console, and realized there was a problem with unpickling the model:
WARNING:pystan:dlopen(/var/folders/8t/0hdwf_0n7n73x1jjlb6g0p180000gn/T/tmpxzeuq7v1/stanfit4anon_model_35bf14a7f93814266f16b4cf48b40a5a_7237902482839548574.cpython-35m-darwin.so, 2):
Library not loaded: @rpath/./libstdc++.6.dylib
I did conda install libgcc
and everything is working fine now.
Sorry and thanks.

@simonb83: I got the same error as you did, and I followed your solution by installing libgcc onto my Anaconda. But now I still get the same error message;p
from prophet.
Can you try installing prophet through conda?
conda install -c conda-forge fbprophet
from prophet.
I already did that. When I did not include the last line 'm.fit(HAN_BIKE)', the whole code still executes perfectly. I only got that error message when including this line. The whole code is the following:
`import pandas as pd
import numpy as np
from fbprophet import Prophet
datapath = "[file directory]"
HAN_BIKE = pd.read_csv(datapath+"HAN-BIKE_1month_CompletedOrders.csv")
HAN_BIKE = HAN_BIKE.drop("hourr", axis=1)
HAN_BIKE['to_char'] = pd.DatetimeIndex(HAN_BIKE['to_char'])
HAN_BIKE = HAN_BIKE.rename(columns={'to_char': 'ds',
'completed_orders': 'y'})
m = Prophet(interval_width = 0.95)
m.fit(HAN_BIKE)`
