ImportError

[davidguo-7]

Hello!

When I was trying to import some kats functionalities on my Jupyter Notebook, it came back with a error message as below:

ImportError Traceback (most recent call last)
in
----> 1 from kats.detectors.outlier import OutlierDetector

~\Anaconda3\lib\site-packages\kats_init_.py in
1 from . import consts # noqa
----> 2 from . import utils # noqa
3 from . import detectors # noqa
4 from . import models # noqa
5 from . import tsfeatures # noqa

ImportError: cannot import name 'utils' from partially initialized module 'kats' (most likely due to a circular import) (C:\Users\49683\Anaconda3\lib\site-packages\kats_init_.py)

Anyone knows how to resolve this issue? Thanks in advance!

Hi @davidguo-7,

Are you able to run this notebook from the tutorials? It has an example using OutlierDetector in it.

[davidguo-7]

Hi @jeffhandl

Yes, I am taking reference from this tutorials. But the error message came out in the first step which imported the function. So, I can't follow the remaining tutorials!

[jeffhandl]

Hi @davidguo-7,

We are trying to understand how you are getting this error. Can you give us the sequence of steps that led to this error so we can reproduce it and try to solve it?

[davidguo-7]

@jeffhandl Hi,

Please the attached screenshot for the error. It's quite strange. When I import TimeSeriesData, it works. But for importing any other functionalities, always failed.

[YachaoDong]

Same error. Request an answer to this error.

[jeffhandl]

@YachaoDong @davidguo-7 Can you give me the steps that you used to install Kats?

There was a problem when installing fbprohet:

ERROR: Failed building wheel for fbprophet`

So I reinstalled fbprohet and kasts, and the installation was successful. This error appears when I run python to import kats：
>>> import kats Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/yachao/miniconda3/lib/python3.7/site-packages/kats/__init__.py", line 2, in <module> from . import utils # noqa ImportError: cannot import name 'utils' from 'kats' (/home/yachao/miniconda3/lib/python3.7/site-packages/kats/__init__.py)

I used conda to create another virtual environment. The same error occurs after installation and operation.
>>> import kats Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/yachao/miniconda3/envs/dong/lib/python3.8/site-packages/kats/__init__.py", line 2, in <module> from . import utils # noqa ImportError: cannot import name 'utils' from partially initialized module 'kats' (most likely due to a circular import) (/home/yachao/miniconda3/envs/dong/lib/python3.8/site-packages/kats/__init__.py)

Thank you for paying attention to this problem and solving this error！

@YachaoDong @davidguo-7 Can you give me the steps that you used to install Kats?

Then I re-created a conda virtual environment, and then ran the following steps:
conda install -c conda-forge fbprophet
pip install kats
python
<<from kats.consts import TimeSeriesData
<< from kats.models.prophet import ProphetModel, ProphetParams
error:

update
I found that the path is empty
miniconda3/envs/ts/lib/python3.7/site-packages/kats/
only two files init.py and consist.py

Then I copied other kats packages into it， but the error still appeared
`

update

I found that when using "pip install kats”, do not use the mirror source. If you use the mirror source, there are no files in the installed kats package. It may be because kats is a new library.
I installed successfully using pip without a mirror source, although the speed is a bit slow.
FYI

[davidguo-7]

@YachaoDong @jeffhandl Aha, great man! It works! If i install kats from the original source, thing goes well! Thank you!

[jeffhandl]

Awesome, @YachaoDong @davidguo-7 is this issue resolved then?

[orthosku]

How did you install it from the original source? I still can't seem to get it to work.

[abc2192233]

How did you install it from the original source? I still can't seem to get it to work.
This may be useful.
