kandi X-RAY | forceps Summary
Have you ever needed to copy a given user from a production database into your local box in order to debug some obscure bug?. Forceps lets you copy related models from one database into another. The source and target databases must support an active record connection. Typically, your source database is a remote production database and your target database is a local development one.

QUESTION
I have recently started learning python to develop a predictive model for a research project using machine learning methods. I have used OneHotEncoder to encode all the categorical variables in my dataset
...ANSWER
Answered 2020-Jun-18 at 14:38ohe.categories_
is a list of arrays, one array for each feature. You need to flatten that into a 1D list/array for pd.DataFrame
, e.g. with np.concatenate(ohe.categories_)
.
But probably better, use the builtin method get_feature_names
.
QUESTION
I'm trying to reformat some data from an API and I'm having trouble getting it the way I need. I need everything to be flattened and my second map function (attMap) is returning them with the an index as the key value?
...ANSWER
Answered 2019-Sep-03 at 16:17Array.map always returns an array, since what you want is a generic object, map is not what you want.
QUESTION
I need to merge pairs of adjacent records in a recordset. Applying a GroupBy gets me part way to my result, but is over-achieving - it is merging invalid pairs.
My GroupBy key contains 3 Attrs:
- Dept
- Area
- ItemNo
This should suffice to identify the unique PAIRS of rows, but I also may have instances where "ItemNo" = 0 (due to holes/Nulls in my client's data). There is no other opportunity in the data to uniquely identify the records. My Problem: A Dept/Area may have MANY "0" ItemNos.
I tried adding the criteria "ItemNo <> 0", but the result is now MISSING these rows. I need them, just NOT to be included in the GroupBy.
Data for Illustration:
...ANSWER
Answered 2018-Sep-24 at 18:15Maybe not optimal, but does give the desired result:
Broke the query into 2 parts -
1) GroupBy Query with ItemNo <> 0
2) Select Query with ItemNo = 0
Then, UNION the above 2 results back together.
