Hey team, 2 questions: 1. I can't seem to see my runs in hamilton UI - not sure what I'm doing wrong 2. my

to_parquet

is not working, and somehow my

df

is a dict, and not a df despite using the pandas

result_builder

. a. it created a df before using Builder pattern for my driver.

Hi Amirali! I think it should be a simple fix. In this case,

.with_adapters()

expects multiple adapters, not a list of adapters. Rewriting the code to:

dr = (
  driver.Builder()
  .with_modules(*modules)
  .with_adapters(tracker, rga)
  .with_materializers(saver)
  .build()
)

Should properly setup the pandas result builder and the Hamilton tracker to populate the UI. Then, to materialize the result, you will have to call

.execute(["features__parquet"])

, in other words, the

id

you set in the

to.parquet

object. When requesting

.execute(["output_data"])

you are producing the dataframe, but not the

parquet

file, which is the next node in the DAG. This gives you some control over when you want to produce the file or not

woww thanks a ton! solved

Nice! This should error out, too…
