download_samples_by_ids

edgeimpulse.data.download_samples_by_ids(
	sample_ids: int | List[int],
	api_key: str | None = None,
	timeout_sec: float | None = None,
	max_workers: int | None = None,
	show_progress: bool | None = False,
	pool_maxsize: int | None = 20,
	pool_connections: int | None = 20
) ‑> List[edgeimpulse.data.sample_type.Sample]
Download samples by their associated IDs from an Edge Impulse project. Downloaded sample data is returned as a DownloadSample object, which contains the raw data in a BytesIO object along with associated metadata. Important! All time series data is returned as a JSON file (in BytesIO format) with a timestamp column. This includes files originally uploaded as CSV, JSON, and CBOR. Edge Impulse Studio removes the timestamp column from any uploaded CSV files and computes an estimated sample rate. The timestamps are computed based on the sample rate, will always start at 0, and will be in milliseconds. These timestamps may not be the same as the original timestamps in the uploaded file.
Parameters
sample_idsint | List[int]
api_keystr | None = None
timeout_secfloat | None = None
max_workersint | None = None
show_progressbool | None = False
pool_maxsizeint | None = 20
pool_connectionsint | None = 20
Returns
List[edgeimpulse.data.sample_type.Sample]

get_filename_by_id

edgeimpulse.data.get_filename_by_id(
	sample_id: int,
	api_key: str | None = None,
	timeout_sec: float | None = None
) ‑> str | None
Given an ID for a sample in a project, return the filename associated with that sample. Note that while multiple samples can have the same filename, each sample has a unique sample ID that is provided by Studio when the sample is uploaded.
Parameters
sample_idint
api_keystr | None = None
timeout_secfloat | None = None
Returns
str | None

​
get_sample_ids

edgeimpulse.data.get_sample_ids(
	filename: str | None = None,
	category: str | None = None,
	labels: str | None = None,
	api_key: str | None = None,
	num_workers: int | None = 4,
	timeout_sec: float | None = None
) ‑> List[edgeimpulse.data.sample_type.SampleInfo]
Get the sample IDs and filenames for all samples in a project, filtered by category, labels, or filename. Note that filenames are given by the root of the filename when uploaded. For example, if you upload my-image.01.png, it will be stored in your project with a hash such as my-image.01.png.4f262n1b.json. To find the ID(s) that match this sample, you must provide the argument filename=my-image.01. Notice the lack of extension and hash. Because of the potential for multiple samples (i.e., different sample IDs) with the same filename, we recommend providing unique filenames for your samples when uploading.
Parameters
filenamestr | None = None
categorystr | None = None
labelsstr | None = None
api_keystr | None = None
num_workersint | None = 4
timeout_secfloat | None = None
Returns
List[edgeimpulse.data.sample_type.SampleInfo]

​
infer_from_filename

edgeimpulse.data.infer_from_filename(
	sample: edgeimpulse.data.sample_type.Sample,
	file: str
) ‑> None
Extract label and category information from the filename and assigns them to the sample object. Files should look like this my-dataset/training/wave.1.cbor where wave is the label and training is the category. It checks if there is training, testing or anomaly in the filename to determine the sample category.
Parameters
