Describe the bug

when i play your demo: /example/train_neural_network. it shows:

2019-03-06 14:50:56,821 - pyswarms.single.global_best - INFO - Optimize for 1000 iters with {'c1': 0.5, 'c2': 0.3, 'w': 0.9}

Hi @olixu , welcome to PySwarms!

Thank you for raising this, we are already aware of the issue (see #264 ) and are currently working on updating them. Perhaps you could work on one, if you are interested?

[lcyuanjiang]

obviously, the optimizer function doesn't have the 'print_step' and 'verbos' interface

Hi @lcyuanjiang , would you like to contribute in updating the documentation?

[ArtificialZeng]

the same situation.

[ArtificialZeng]

Did you solved this???

[lcyuanjiang]

optimize(fx.sphere,inters=20000) ,get rid of the"print_step="

[lcyuanjiang]

just get rid of the “print step”in optimize发自我的iPhone------------------ Original ------------------From: 曾小健 <[email protected]>Date: Wed,Apr 10,2019 1:02 PMTo: ljvmiranda921/pyswarms <[email protected]>Cc: lcyuanjiang <[email protected]>, Mention <[email protected]>Subject: Re: [ljvmiranda921/pyswarms] unexpected keyword argument 'print_step'(#317)Did you solved this??? —You are receiving this because you were mentioned.Reply to this email directly, view it on GitHub, or mute the thread. {"api_version":"1.0","publisher":{"api_key":"05dde50f1d1a384dd78767c55493e4bb","name":"GitHub"},"entity":{"external_key":"github/ljvmiranda921/pyswarms","title":"ljvmiranda921/pyswarms","subtitle":"GitHub repository","main_image_url":"https://github.githubassets.com/images/email/message_cards/header.png","avatar_image_url":"https://github.githubassets.com/images/email/message_cards/avatar.png","action":{"name":"Open in GitHub","url":"https://github.com/ljvmiranda921/pyswarms"}},"updates":{"snippets":[{"icon":"PERSON","message":"@ArtificialZeng in #317: Did you solved this???"}],"action":{"name":"View Issue","url":"#317 (comment)"}}} [ { "@context": "http://schema.org", "@type": "EmailMessage", "potentialAction": { "@type": "ViewAction", "target": "#317 (comment)", "url": "#317 (comment)", "name": "View Issue" }, "description": "View this Issue on GitHub", "publisher": { "@type": "Organization", "name": "GitHub", "url": "https://github.com" } } ]

Hopefully this is already solved. Closing this issue
