How do I upgrade my usage plan?

To upgrade your usage plan, please contact sales@peltarion.com.

Where do I ask for help?

If you have any questions about the Peltarion platform functionality, please contact support@peltarion.com.

What do I do when my quota plan has reached the limit?

When your organization quota plan has reached the limit, you should contact sales@peltarion.com to discuss renewing the quota payment plan.

You can still log on to the Platform. This will allow you to both view and delete your data, experiments, deployments, and projects.

However, you will no longer be able to:

  • start new projects

  • upload new data

  • create new experiments

  • run or resume experiment training

  • create new deployment

  • enable deployments

Notifications will remind your users that the organization’s quota plan has reached its limit.

Technical requirements

In early explore phase there are a number of technical requirements to consider when using Peltarion Platform.

Supported browsers

Chrome only, from version 66.0+.

Resource usage

An experiment can run for at most 4 hours.

Requirements on imported datasets

Data preprocessing

ETL (Extract, Transform, Load) must be done outside the Platform.

Dataset file size

The maximum size when you upload a file is 2GB.

Note
There is no size limit if you import a dataset file from an URL.

Data formats supported by the Peltarion Platform

File formats supported for data import:

  • csv

  • npy

  • png

  • zip

CSV FILE SPECIFICATIONS

The csv file is a tabular comma-separated data file containing headers. Supported encoding is UTF-8. Data containing special characters is only supported in case of UTF-8 encoding. Find out more in known issues.

The csv-file must contain a constant number of columns.

The data need to be well-formatted, that is, the data type in each column is consistent and contains no empty- or null-values.

Example: List traffic on a specific location at a specific date and time.

Supported subtypes

  • f4, 32-bit floating-point number

  • string

  • integer

Csv file limitations

  • Categorical encoding categories: 2 000

  • Maximum number of rows: 10 000 000

  • Maximum number of columns: 5 000

NPY FILE SPECIFICATIONS

The npy file is a binary file format for a one NumPy array where NumPy is a library for the Python programming language.

Supported subtypes

  • f4, 32-bit floating-point number

Upload

The npy can be used to import images, then each pixel is represented as a floating-point number.

In a raw npy file samples are assumed to be arranged along the first dimension, for example, if the npy array have dimensions (1000, 20, 10, 3) the platform will treat it as 1000 separate tensors with height 20, width 10, and 3 channels.

Little-Endian byte order is supported. Fortran order not supported.

The platform supports multi-class classification for targets of higher dimensionality, e.g., a target that is a vector of different classes, or a target that is an image with one class per pixel.

In this kind of classification problem the target data is represented by a numpy array, where the last axis is interpreted as the class label and needs to be one-hot-encoded before importing into the platform.

Visualization on the Datasets view

Visualisation of npy files depends on the number of dimensions. Find out more in known issues.

Example: A 10x10 pixel grayscale image will consist of 100 floating-point numbers. If the image is a 10x10 pixel RGB image it will consist of 300 floating-point numbers.

PNG FILE SPECIFICATIONS

Supported subtypes

  • 24 bit, 256x256 pixel

Note
When png files are imported into the Platform they are converted to npy.

ZIP FILE SPECIFICATIONS

The zip file is used to bundle image or numpy files together. Supported formats for the individual files are png, jpg and npy.

The zip file must also contain an index.csv file with at least one column with one row per image containing the relative path to each image. The index.csv file may also contain other columns which will be handled the same way as in a standalone csv file.

All images or numpy files must be of the same format and have the same dimensions.
