Python dataset support ubuntu 19/20

[epa095]

Issue: When attempting to download a dataset on ubuntu 19.10 I get NotImplementedError: Unsupported Linux distribution ubuntu 19.10.

It seems like the problem is that the dotnetcore2 pip package actually only supports ubuntu 18. But ubuntu 20.04 is the new LTS, so it makes sense to support it (and also ubuntu 19).

Also, can we agree that it is a bit of an architecture-smell when downlading some csv-files (the dataset) causes a dependency to go look for a distro-specitic tar-file for a custom installation of a third dependency? I don't know whats the best solution, but this cant be it.

Hi Erik,

Were you downloading an AML Dataset from AML workspace?
Or were you downloading the CSV file?
Could you help to provide more details about the interface you are using?
Thanks!

Hi @SturgeonMi !
I was attempting to follow along this tutorial on my ubuntu 19.10 linux, but I got the above mentioned problem when I got to the step "Download the MNIST dataset". It crashes on the step MNIST.get_file_dataset, because it ends up calling attemp_get_deps in the file runtime.py in the package dotnetcore2.

My relevant versions:
dotnetcore2==2.1.13
azureml-opendatasets==1.4.0
azureml-sdk==1.4.0
azure-core==1.4.0
ubuntu 19.10

Hi Erik,

We fixed related bug in Open Datasets SDK.

Could you help to try below steps?

Please ensure you are using the latest Azure Open Datasets SDK. You can get install the latest SDK by Running the following commands"
!pip uninstall -y azureml-opendatasets
!pip install azureml-opendatasets

Also here is the latest version of the tutorial notebook: https://github.com/Azure/MachineLearningNotebooks/blob/master/tutorials/image-classification-mnist-data/img-classification-part1-training.ipynb

Thanks!

Hi @SturgeonMi, the latest version of azureml-opendatasets I see on pypi is 1.4.0, and as you can see from my previous comment that is the version I am already using.

Hi Erik, we opened a bug for dotnetcore2 issue.
Once it's fixed, will update here.
