M4 experiment is not avalable

[Dolores2333]

The M4 dataset url link in the script is not available. Though I mannually downloaded the datasets from M4Competition , the make run command still fails.

Wired. If I move download method in dataset/m4.py out of the class and run it first then the download process is ok. But errors reported if I use download method as a class method which is exactly use by the author.

Encountered this issue too because the download links for the M4 dataset are dead. Solved it by replacing them with the following links:
TRAINING_DATASET_URL = 'https://git.islab.ntua.gr/stralex/m3-m4/raw/master/data/M4DataSet.zip'
TEST_DATASET_URL = 'https://git.islab.ntua.gr/stralex/m3-m4/raw/master/data/M-test-set.zip'
INFO_URL = 'https://git.islab.ntua.gr/stralex/m3-m4/raw/master/data/M4Info.csv'
