Got "TypeError: 'generator' object is not subscriptable" on my Ubuntu machine

[Michael89]

Hi I'm trining to use your grate lib for tuning hyperparameters for my NN, but for some reason I got this error:

  File "/home/michael/work/oanda/src/oanda/trend_prediction/find_optimal_model.py", line 124, in <module>
    main()
  File "/home/michael/work/oanda/src/oanda/trend_prediction/find_optimal_model.py", line 116, in main

    assert order[-1] == expr
TypeError: 'generator' object is not subscriptable

Everything work nice when I tried it on my mac book but when I start it on my desktop (which I build for NN training) I got this error and don't know what to do.

Python 3.5.2

Find a quick fix. I noticed that I have networkx-2.0 version on ubuntu and networkx-1.11 on mac so I just downgrade it on ubuntu and it starts working.

Thanks @Michael89 for your quick fix! I confirm that networkx-2.0 is the culprit of the error and downgrading to version 1.11 does the trick.

[charlesreid1]

Thanks for this. For anyone wondering how to downgrade:

$ pip install networkx==1.11

Seems this is still an issue

[michaelmior]

This was fixed in #319 but you'll either have to run with the code from the repository or wait for the next release.

Do pip install --upgrade git+git://github.com/hyperopt/hyperopt.git until a new release has been made.

Hi guys!
Looks like it is still an issue on my Mac ( Darwin Kernel Version 16.6.0: Fri Apr 14 16:13:31 PDT 2017; root:xnu-3789.60.24~4/RELEASE_X86_64 x86_64) with Python 3.6.3

Just did 'pip install --upgrade git+git://github.com/hyperopt/hyperopt.git', downgraded networkx but nothing helps...

Thanks in advance for any clues.

[michaelmior]

Don't really see how this would be possible since order is explicitly converted to a list. Can you check that hyperopt/pyll/base.py in your hyperopt installation matches what's in master?

[olddaos]

Excuse me please and thank you for prompt reply. I already restarted iPython notebook and everything is fine. Cheers, Alexey пятница, 15 июня 2018 г. пользователь Michael Mior написал:

Wondering what's blocking creating a new release. Having unpinned versions isn't healthy or easy to maintain as general creating a new release is rather easy.

[michaelmior]

I don't have permissions to publish a new release myself, but you can pin your version to a specific git commit. Agreed that a released version would still be great though.

[maxpumperla]

I can do a release next week

[nqnhu1]

Have anyone gotten to solve it yet please? I got a similar error 'int' object is not subscriptable. I'm having a hard time trying to figure it out

[michaelmior]

@nqnhu1 Try using the version of hyperopt on the master branch.
