Stoked to keep working with this program!

I am attempting to run the wolfcamp_single example and I am running into an error: AttributeError: 'DataFrame' object has no attribute 'as_matrix'

Looking at the Electofacies definition when defining minibatch_input:

components = pd.DataFrame(data = pc.transform(X), index = df[not_null_rows].index)

minibatch_input = components.as_matrix()

it appears that "df.as_matrix()" has depreciated in a the newer version of pandas. I cannot seem to get the correct command to get the example to run. Could someone help?

You are working on wolfcamp_single.py?

I used this about a year ago and do not remember how I got it working, but on mine I not even see where pandas is loaded?

@Philliec459 Yes, I am working with the wolfcamp_single.py

If you look at the electrofacies source code here: https://github.com/toddheitmann/PetroPy/blob/master/petropy/electrofacies.py it requires the import of numpy and pandas.

The example wolfcamp_single.py calls ptr.electrofacies on line 147:

logs = ptr.electrofacies(logs, f, electro_logs, 6, log_scale = ['RESDEEP_N'])

Jul 09 '20 19:07 cdmeyer23

As I said, I set this up ages ago and do not have all the details.

I definitely see the pandas in this module. Thanks. Let me see if I can retrace my setup and see what I can come up with. I had some issues and solved them, but back then I was not documenting how I did what.

In the plot below I see the Electrofacies, but I have no idea of how I did this.

Did you use setup from Todd’s GitHub?

I did install Petropy and I see that it resides in my …./Anaconda/Lib/site-packages/petropy subdirectory. It was either a pip or "python install setup.py" type of install that I did back in October of last year. Too long ago to remember the details.

I also see from the emails that they were working in petropy back in April. I have not upgraded and do not know if the changes are affecting you now or not. Below is my electrofacies.py if that is any help. Below that is my wolfcamp_single.py.

I do remember having to make some mods to get it to run, but did not take any notes back then on what I did to get it running. I could have removed some code too???? However, I do have petropy working on my system now. At least on my system it does take a while to run.

@Philliec459 Thank you so much helping me out, I think the only way to get around it for now is to use the setup that is provided. I didn't see that before. While it is frusterating to have to run it with older versions of numpy and pandas, which makes other code that is run with it not function properly, at least it works that way.

Thanks again!

I think that it is easiest to load petropy to work from it.

As a Petrophysicist, this is probably the first python project that I worked on when I was getting started with Python. Now that I look back there are a lot of good things here that I want to pursue further.

I have my own GitHub with some petrophysical repositories that might help you too, but lately I am into Object Detection and so my repositories are deviating from petrophysics.

https://github.com/Philliec459?tab=repositories https://github.com/Philliec459?tab=repositories

My next goal will be to scan a log and do almost object detection picking out invervals, electrofacies, pay just from the log signatures. I will be using the Equinor Volve dataset for this.
