In colab I do:
import cmdstanpy cmdstanpy.install_cmdstan() print(cmdstanpy.__version__)
INFO:cmdstanpy:Install directory: /root/.cmdstanpy INFO:cmdstanpy:Downloading CmdStan version 2.26.1 INFO:cmdstanpy:Download successful, file: /tmp/tmplpsqqk0x INFO:cmdstanpy:Unpacked download as cmdstan-2.26.1 True 0.9.5
I then have no problem fitting my model, and I get a fit object:
I used to run
fit.draws_pd(['epsilon_steps']) but this and everything else I’ve tried from the documentation (e.g.
fit.draws_as_dataframe()) don’t work.
thanks so much !!
