QUESTION
I'm trying to make a data labeling in a table, and I need to do it in such a way that, in each row, the index is repeated, however, that in each column there is another Enum class.
What I've done so far is make this representation with the same enumerator class.
A solution using the column separately as a list would also be possible. But what would be the best way to resolve this?
...ANSWER

you can use a dict
mapping. You can avoid loops if you flatten your dataframe:
QUESTION
I have a dataframe that contains a column that includes strings separeted with semi-colons and it is followed by a space. But unfortunately in some of the strings there is a semi-colon that is not followed by a space.
In this case, This is what i'd like to do: If there is a space after the semi-colon we do not need a change. However if there are letters before and after the semi-colon, we should change semi-colon with space
i have this:

QUESTION
Objective: Generate a down-sampled FileDataset using random sampling from a larger FileDataset to be used in a Data Labeling project.
Details: I have a large FileDataset containing millions of images. Each filename contains details about the 'section' it was taken from. A section may contain thousands of images. I want to randomly select a specific number of sections and all the images associated with those sections. Then register the sample as a new dataset.
Please note that the code below is not a direct copy and paste as there are elements such as filepaths and variables that have been renamed for confidentiality reasons.

Install data-factory-airflow-dags
Create the following pools: image_preprocessing with N slots, where N is less than the number of vCPUs available on the machine remote_file_copy with N slots, where N should be 1 or 2 to avoid saturating network IO
In Airflow config file, add a [spm] section with the following entries: SPM_DIR: path to the root folder of SPM 12.
In Airflow config file, add a [mipmap] section with the following entries (required only if MipMap is used for ETL): DB_CONFIG_FILE: path to the configuration file used by MipMap to connect to its work database.
In Airflow config file, add a [data-factory] section with the following entries: DATASETS: comma separated list of datasets to process.

For each dataset, configure the [data-factory:<dataset>:reorganisation] section if you need to reorganise an input folder containing only files or folders that will be split into several folders, one per visit for example: INPUT_FOLDER: Folder containing the original imaging data to process. This data should have been already anonymised by a tool INPUT_FOLDER_DEPTH: depth of folders to explore while scanning the original imaging data to process. INPUT_CONFIG: List of flags defining how incoming imaging data are organised, values are defined below in the preprocessing section. MAX_ACTIVE_RUNS: maximum number of reorganisation tasks in parallel FOLDER_FILTER: regex that describes acceptable folder names. Folders that does not fully match it will be discarded.

For each dataset, now configure the [data-factory:<dataset>:preprocessing] section: INPUT_FOLDER: Folder containing the original imaging data to process. This data should have been already anonymised by a tool. Not required when the reorganisation pipelines have been used before. INPUT_CONFIG: List of flags defining how incoming imaging data are organised, values are boost: (optional) When enabled, we consider that all the files from a same folder share the same meta-data. The processing is (about 2 times) faster. This option is enabled by default. session_id_by_patient: Rarely, a data set might use study IDs which are unique by patient (not for the whole study). E.g.: LREN data. In such a case, you have to enable this flag. This will use PatientID + StudyID as a session ID. visit_id_in_patient_id: Rarely, a data set might mix patient IDs and visit IDs. E.g. : LREN data. In such a case, you have to enable this flag. This will try to split PatientID into VisitID and PatientID. visit_id_from_path: Enable this flag to get the visit ID from the folder hierarchy instead of DICOM meta-data (e.g. can be useful for PPMI). repetition_from_path: Enable this flag to get the repetition ID from the folder hierarchy instead of DICOM meta-data (e.g. can be useful for PPMI).
