ImportError: cannot import name 'get_forecasting_splits' from 'tsai.data.validation'

Hi, i am learning the tutotial on data preparation: https://timeseriesai.github.io/tsai/data.preparation.html#forecasting-data-preparation in this doc there is a line: from tsai.data.validation import get_forecasting_splits when i run this, i got error:

ImportError Traceback (most recent call last) Cell In[4], line 1 ----> 1 from tsai.data.validation import get_forecasting_splits 3 fcst_history = 10 4 fcst_horizon = 5

ImportError: cannot import name 'get_forecasting_splits' from 'tsai.data.validation' (d:\Anaconda\envs\py39\lib\site-packages\tsai\data\validation.py)

my configuration os : Windows-10-10.0.19041-SP0 python : 3.9.16 tsai : 0.3.4 fastai : 2.7.10 fastcore : 1.5.27 torch : 1.12.1+cu113 device : 1 gpu (['NVIDIA GeForce GTX 1650']) cpu cores : 4 threads per cpu : 2 RAM : 15.84 GB GPU memory : [4.0] GB

BTW, I am going through the doc and try to run the code line by line, I encounterd several other similar errors where 'ImportError: cannot import name ***', I go to check my installed tsai package and indeed didn`t found the function, the function only appears in tsai-main repository. What's wrong with my tsai installation? Do I need to replace my installed file with the corresponding one in tsai-main?

Hi @langslike, You need to upgrade to tsai>=0.3.5. This is some new functionality only available as of release 0.3.5.

Thanks, Is it possible that users can choose to read the exact version of docs for his own installation, like: https://pytorch.org/docs/versions.html I think it might be helpful.

Thanks for your suggestion @langslike. Unfortunately, nbdev, the library I use to create the code, tests, and documentation, doesn't allow doc versioning. I recommend users upgrade to the most recent stable version in pip/ conda.
