After running a model for a long time, I tried dumping out the parameters using bin/stansummary output.csv and got
Error: error reading header
libc++abi.dylib: terminating with uncaught exception of type std::invalid_argument: Error with header of input file in parse
Abort trap: 6
I tried running against the result of the bernoulli sample and it showed the parameter fine.
What can I do with this error?
