Error of Network Traffic Model Forecasting

[MengleiZhang]

I got the following error when running the following example: network_traffic_model_forecasting.ipynb. However, when I tried the older version of this file (before the update on Aug 10), there was no error. Can you check?

I installed the analytics-zoo using pip install analytics-zoo.

forecaster = LSTMForecaster(past_seq_len=x_train.shape[1], input_feature_num=x_train.shape[-1], output_feature_num=y_train.shape[-1], hidden_dim=16, layer_num=2, lr=0.001)

TypeError Traceback (most recent call last) /tmp/ipykernel_3636247/1497806761.py in 8 hidden_dim=16, 9 layer_num=2, ---> 10 lr=0.001)

TypeError: init() got an unexpected keyword argument 'past_seq_len'

Hi,

We updated our API and had some improvement on forecaster since last release and the notebook on master branch reflect the changes. There are two options to make things work.

1. (recommended) upgrade the analytics-zoo to our weekly-built version by

pip install --pre --upgrade analytics-zoo[automl]

and continue using the notebooks on master branch

2. Continue using analytics-zoo 0.11.0 released version and notebooks on tag 0.11.0: https://github.com/intel-analytics/analytics-zoo/blob/v0.11.0/pyzoo/zoo/chronos/use-case/network_traffic/network_traffic_model_forecasting.ipynb

Method 1 works. Thank you.

Hi I tried the above method but still not able install

Hi I tried the above method but still not able install

Oh I just found you are using windows, it seems that we only release whl for linux and macos... @Shubhamshrimali

if you are using linux/macos/wsl

The command seems to work just fine.

Some possible fixes are:

• check your network connection
• unset the 3rd party mirror source you may set for pip and use the default source
• download the whl directly and install by pip install .[automl] from here

I am able to install other file like tensorflow. so i can say there is no network issue

unset the 3rd party mirror source you may set for pip and use the default source :- i freshly build my system so i don't have any 3rd party mirror source

download the whl directly and install by pip install .[automl] :--

This is windows machine

[TheaperDeng]

yeah I believe the issue is caused by platform conflict. analytics-zoo is tested throughly on mac and linux(or wsl on windows). Sadly we have not supported windows yet. The easiest way might be using WSL in windows. @Shubhamshrimali
