Time series add-on installation fails

[kielhauser]

(transferred from biolab/orange3)

Orange version

3.3.6 (git revision ee294bc) on OSX 10.11 and Windows 10

Expected behaviour

The time series add-on should install without problems via the Options -> Add-on -> Orange3-Timeseries -> Install

Actual behaviour

An error is given (see attached files) both on Windows and OSX

Steps to reproduce the behavior

(see expected behaviour)

The solution on Windows is to install numpy, scipy, and statsmodels from prebuilt packages by Cristoph Gohlke (ensure the architecture and Python version match). E.g.

pip install numpy-1.11.1+mkl-cp34-cp34m-win32.whl \
            scipy-0.17.1-cp34-cp34m-win32.whl \
            statsmodels-0.6.1-cp34-none-win32.whl

where pip is the correct pip from the virtual environment where Orange is installed. Then, the add-on should install on Windows. Unfortunately, I don't see an easy way around on Windows.

Thanks for the windows solution - for OSX i found a workaround after some trial and error: removing the binary version of orange and reinstalling it from source using python3 / pip3 (using python/pip doesn't work though)

On OS X, the statsmodels project provides prebuilt wheel packages for OS X. Unfortunately, they weirdly only conditionally include pandas package in the install requirements, which makes the package not installable since the pandas dependency, which should be a hard dependency, obviously, is not satisfied. The solution is to pip install pandas before installing the add-on on OS X (with the correct pip). This may be saved altogether with the most recent version of statsmodels (==0.8.0, for which wheels are not available).

Yes, Orange3-Timeseries as well as Orange in whole requires Python 3. Thanks.

Could we somehow check the OS and perhaps remove Timeseries from the list? At least until we (hopefully) move to Anaconda?

Hi, I know this is an ongoing issue, but do you think there is any chance the timeseries add-on installation can work any time soon? I'm afraid I have no idea how to install it through Anaconda or whatever.

[kernc]

It should work if you:

1. Download and install Orange (Standalone Miniconda installer).
2. Go to menu Options > Settings, tab Add-ons, check "Install add-ons with conda".
3. Go to menu Options > Add-ons and install Timeseries add-on, successfully.

[lmnoeme]

Thanks for your response. That's what I did and it failed. Same error message as decribed at https://github.com/biolab/orange3/issues/1691

[kernc]

Did you do the 2. step above? The check is not there by default.

[lmnoeme]

Thanks for pointing that out to me. I had skipped step 2 the first time. I have done it this time but it still doesn(t work. The error message is still the same.

I'm using 64-bit Windows. Can the problem stem from that?

[lmnoeme]

All right, I have uninstalled Orange, then installed Anaconda and reinstalled Orange from the Anaconda navigator. It's working now. Thanks for your support.

[lmnoeme]

I've just realized that Anaconda does not feature the latest version of Orange. It currently has version 3.4.1 Do you know if there is a way to get the latest version under Anaconda?

[astaric]

You need to add the conda-forge channel.

Might be useful for those on Windows without any conda (Orange 3.11.0): 1) Install Microsoft Windows SDK 7.1 (www.microsoft.com/download/details.aspx?id=8279) 2) If setup failes with PermissionError: [WinError 5] Access is denied: 'C:\\Users\\User\\AppData\\Local\\Temp\\pip-o29stj1u-uninstall\\program files\\orange\\lib\\site-packages\\scipy\\integrate\\lsoda.pyd' run Orange as admin during setup (right click -> Run as administrator).

Solution is as suggested by @astaric.
