Hi there, I just built an mmm model using DelayedSaturatedMMM… I’m trying to create budget allocation scenario based on this example ()… However, when i called out the code block below, it gave me an error that says ‘DelayedSaturatedMMM’ object has no attribute ‘allocate\_budget\_to\_maximize\_response’

Here’s my code:

```auto
## Load pre trained model
mmm = DelayedSaturatedMMM.load("direct_mmm_with_lift_test_v2.nc")

total_budget = 1  
channels = spend_cols
budget_per_channel = total_budget / len(channels)
initial_budget_dict = {channel: budget_per_channel for channel in channels}
min_budget, max_budget = 0.05, .4
budget_bounds = {channel: [min_budget, max_budget] for channel in channels}

menten_params = mmm.compute_channel_curve_optimization_parameters_original_scale(
    method="michaelis-menten"
)

#### the code block below raised an error ####
response = mmm.allocate_budget_to_maximize_response(
    budget=total_budget,
    num_days=8,
    time_granularity="weekly",
    budget_bounds=budget_bounds
)

```

Hello,

Can you show which PyMC-Marketing version are you using?

Hello,  
Did this error get resolved? I am also facing the same error and am new to pymc so would like some direction.

What version of pymc-marketing are you using? If you are not using the most recent version, I would suggest trying to install that first.

~~If I’m correct this is a general Python issue having to do with the current working directory. If the current working directory has a `pymc_marketing` subdirectory (like a clone of the Git repo), then it will clobber the `pymc_marketing` package which is under `pymc_marketing/pymc_marketing`.~~

~~So make sure that you’re not in the parent directory of a `pymc_marketing` clone, and make sure you don’t have any other directories called `pymc_marketing` that aren’t the actual `pymc_marketing` package.~~

</div>

Can you run the following and show what the output is?

```python
from pymc_marketing.mmm.delayed_saturated_mmm import MMM
[m for m in dir(MMM) if callable(getattr(MMM, m))]

```

Thanks @JenniferSiwu 🙂  
That helped but however now it’s throwing weird budgets which do not add up to the total budget - similar to what you were facing.

Also a qq - for your test data, what metrics are you using for evaluation?

The method is right there, so I’m not sure why you are getting the error saying it’s not. Are you sure you spelled the function name correctly, etc.?

</div>

yes I am. On reinstalling the package it worked. Thank youuuu! Appreciate it! @cluhmann

However the budget that it’s showing is greater than by total budget for example when I used 5 for 500K my total is coming to be 6.83.

I am unsure of why this is happening - can you help me with that?
