fetch_experiments_table()

Fetches a table of experiment metadata, with runs as rows and attributes as columns.

To narrow the results, define filters for experiments to search or attributes to include.

Returns a DataFrame similar to the runs table in the web app. For series attributes, the last logged value is returned.

Parameters

project
str
optional
default: None

Path of the Neptune project, as WorkspaceName/ProjectName.

If not provided, the NEPTUNE_PROJECT environment variable is used.

experiments
str | list[str] | Filter
optional
default: None

Filter specifying which experiments to include.

  • If a string is provided, it's treated as a regex pattern that the experiment names must match.
  • If a list of strings is provided, it's treated as exact experiment names to match.
  • To provide a more complex condition on an arbitrary attribute value, pass a Filter object.

If no filter is specified, all experiments are returned.

attributes
str | list[str] | AttributeFilter
optional
default: None

Filter specifying which attributes to include.

  • If a string is provided, it's treated as a regex pattern that the attribute names must match.
  • If a list of strings is provided, it's treated as exact attribute names to match.
  • To provide a more complex condition, pass an AttributeFilter object.
sort_by
str | Attribute
optional
default: "sys/creation_time"

Name of the attribute to sort the table by.

Alternatively, an Attribute object that specifies the attribute type.

sort_direction
"asc" | "desc"
optional
default: "desc"

Sorting direction of the column specified by the sort_by parameter.

limit
int
optional
default: None

Maximum number of experiments to return. By default all experiments are returned.

type_suffix_in_column_names
bool
optional
default: False

If True, columns of the returned DataFrame are suffixed with :<type>. For example, "attribute1:float_series", "attribute1:string".

If set to False, the method throws an exception if there are multiple types under one path.

Example

Fetch attributes matching loss or configs from two specific experiments:

import neptune_query as nq


nq.fetch_experiments_table(
experiments=["seagull-week1", "seagull-week2"],
attributes=r"loss | configs",
)
