Not sure if anyone else has encountered the same issue. Running the example returns the following error

import pandas as pd
from causalimpact import CausalImpact

data = pd.read_csv('https://raw.githubusercontent.com/WillianFuks/tfcausalimpact/master/tests/fixtures/arma_data.csv')[['y', 'X']]
data.iloc[70:, 0] += 5

pre_period = [0, 69]
post_period = [70, 99]

ci = CausalImpact(data, pre_period, post_period)
print(ci.summary())
print(ci.summary(output='report'))
ci.plot()

Hi @tmpacc90 ,

Apparently you are using some other project of causal impact, this one doesn't have a module named "analysis.py" which is indicated in your traceback.

To use this project, please make sure the code is available in your interpreter lib by running pip install -U tfcausalimpact

Let me know if this helps you,

[tmpacc90]

Thanks. It helps! 😃

Hi! I'm getting the exact same error here, despite doing the pip install -U tfcausalimpact. Do you know what else I can do?

It was working just fine 3 days ago.

Hi @benji931122 ,

Could you please open a new issue for us to further investigate it? Please let us know the version of tfci you currently have and an example of the code you are running, as well as OS and Python version.
