I am running the basic “hello world” tutorial for cmdstanpy found here. The problem I have is that I cannot access the sample summary. I get the following error.

```
RuntimeError: ERROR
The following argument was not expected: --csv_file=/tmp/tmpijc0jg81/stansummary-bernoulli-4-chain-nzo5wr_y.csv
Run with --help for more information.
```

Here is the code I use, it’s copy pasted from the tutorial. I also want to note that I did not have this problem yesterday and earlier in the week with other models. I am also using cmdstanpy in google colabs. Alternatively I tried to run the code in a new colab notebook and got the same error so I have a suspicion it might be a colab problem, but I am not really sure. The version of cmdstanpy I was using earlier this week and today is 0.9.5

```
from cmdstanpy import cmdstan_path, CmdStanModel
bernoulli_stan = os.path.join(cmdstan_path(), 'examples', 'bernoulli', 'bernoulli.stan')
bernoulli_model = CmdStanModel(stan_file=bernoulli_stan)
bernoulli_model.name
bernoulli_model.stan_file
bernoulli_model.exe_file
bernoulli_model.code()
bernoulli_data = os.path.join(cmdstan_path(), 'examples', 'bernoulli', 'bernoulli.data.json')
bern_fit = bernoulli_model.sample(data=bernoulli_data, output_dir='.')
bern_fit.summary()
```
