caltrack hourly method problem

[LiuJingyao18360]

I plan to try EEmeter caltrack hourly method, but there is one line of the code doesn't work. I used the sample data and do exactly the same with the tutorial, but this line of the code just shows error. I wonder if we need a specific version of pandas to run our code? I' m really confused about it, would you please have a look at this problem?

occupancy_lookup_hourly = eemeter.estimate_hour_of_week_occupancy(
preliminary_design_matrix_hourly,
segmentation=segmentation_hourly,
# threshold=0.65 # default
)

The message shows as below:

ValueError Traceback (most recent call last)
ValueError: Buffer dtype mismatch, expected 'Python object' but got 'double'

Exception ignored in: 'pandas._libs.lib.is_bool_array'
ValueError: Buffer dtype mismatch, expected 'Python object' but got 'double'

Thanks for the report. We recommend pandas using 0.23.4, if that helps. You're seeing this in the scripts/tutorial.ipynb, right? Could you send your eemeter and pandas versions to assist with reproducing the error?

Additionally, would you mind pasting in the full traceback, redacted if necessary?

Dear Phil, I've tried pandas 0.21.0 in Anaconda 3 and 0.22.0 in which version Anaconda I forget sorry. They all do not work. The attachment is the error screenshots. Thank you for your concern.

Hi - and the eemeter version?

The attachment does not seem to have gone through. Please paste the traceback text directly?

[LiuJingyao18360]

The eemeter version is 2.7.0. I'm not sure what is the traceback text, is the file I attached? <https://maas.mail.163.com/dashi-web-extend/html/proSignature.html?ftlId=1&name=ucbqiue&uid=ucbqiue%40ucl.ac.uk&iconUrl=https%3A%2F%2Fmail-online.nosdn.127.net%2Fqiyelogo%2FdefaultAvatar.png&items=%5B%22ucbqiue%40ucl.ac.uk%22%5D> [https://mail-online.nosdn.127.net/qiyelogo/defaultAvatar.png] ucbqiue ucbqiue@ucl.ac.uk 签名由 网易邮箱大师<https://mail.163.com/dashi/dlpro.html?from=mail81> 定制 On 7/16/2019 00:06，Phil Ngo<notifications@github.com><mailto:notifications@github.com> wrote： Hi - and the eemeter version?

Hi, @LiuJingyao18360 -

I've tried, but I haven't yet been able to reproduce the error you are getting with the hourly methods code. I recommend using pandas 0.23.4 and eemeter 2.7.1, or using the docker setup (docker-compose build, docker-compose up jupyter, then paste the link into a browser). When you send the attachment by email it doesn't seem to be going through (try looking at this issue on github and you'll see how it appears: #357). The traceback text is the error that python prints out when it fails. I think you've pasted one line of it, but it's generally helpful to see all the lines of the traceback text because it includes references to the lines of code in the library that failed.

[LiuJingyao18360]

The pandas 0.23.4 works well now. Thank you for your help!
