Error in reseting launchpad

launchpad.reset(password)

    self.__name.split(".")[-1])

TypeError: 'Collection' object is not callable. If you meant to call the '_retryable_write' method on a 'Collection' object it is failing because no such method exists.

I recently updated fireworks from 1.2.4 and am now getting this error. I tracked it down and it starts in 1.3.2. For the moment I'm going to roll back, but any suggestions?

Thanks!

Hi Michelle,

For tracking down problems sometimes the changelog is useful:

https://materialsproject.github.io/fireworks/changelog.html

In FWS 1.3.2 for example, we updated the pymongo commands since the newest pymongo, which has many useful updates, no longer supported the old commands.

Can you confirm:

* did you update FWS via one of the procedures listed here: https://materialsproject.github.io/fireworks/installation.html . In particular, if you run "git pull" you need to also do "python setup.py install" or "python setup.py develop".

* what version of pymongo do you have? e.g. "import pymongo; print(pymongo.__version__)"

Best

Hi Michelle,

Going off what Anubhav said, I have had similar errors which were fixed by a pymongo update.

I have the latest pymongo installed:

pymongo==3.6.1

I installed using pip. 

Since it was a pymongo error I thought of that first but since I was at the latest version I wasn't sure where to go from there.

[Michelle Brenner]

Which version of pymongo are you using? Maybe I've gone too far.

[Anubhav Jain]

I am using 3.4.0 but I doubt you've gone too far.

Sorry to keep asking the same thing, but are you sure the updated pymongo is in the same Python environment as your FWS installation?

Best,

Anubhav

Hmm that should work. Firworks requires pymongo==3.6.0

How is your launchpad object being instantiated? E.g., from a file, using LaunchPad(port=xxxxx), etc.?
