Is persim.plot still available?

I'm using Python 3.8 and I have these:

$ pip3.8 list -u

six             1.14.0 
tadasets        0.0.4  
umap-learn      0.3.10 

The code below from http://persim.scikit-tda.org/notebooks/distances.html

import numpy as np
import persim
import persim.plot
import tadasets
import ripser
import matplotlib.pyplot as plt

gives the error

ModuleNotFoundError: No module named 'persim.plot'

Removing the import persim.plot the error

AttributeError: module 'ripser' has no attribute 'plot_dgms' 

appears when calling ripser.plot_dgms().

Any idea how to solve it? Maybe documentation is outdated?

Code

import numpy as np
import persim
#import persim.plot
import tadasets
import ripser
import matplotlib.pyplot as plt

data_clean = tadasets.dsphere(d=1, n=100, noise=0.0)
data_noisy = tadasets.dsphere(d=1, n=100, noise=0.1)

plt.scatter(data_clean[:,0], data_clean[:,1], label="clean data")
plt.scatter(data_noisy[:,0], data_noisy[:,1], label="noisy data")
plt.axis('equal')
plt.legend()
plt.show()

dgm_clean = ripser.ripser(data_clean)['dgms'][1]
dgm_noisy = ripser.ripser(data_noisy)['dgms'][1]

ripser.plot_dgms([dgm_clean, dgm_noisy] , labels=['Clean $H_1$', 'Noisy $H_1$'])

Just to inform, it works if remove import persim.plot and replace ripser.plot_dgms by persim.plot_diagrams.

It would be good to update documentation.

Thanks for catching this, it would be really helpful if you could submit a PR with the doc changes!

I'm not sure if I can use Git but I'll do my best to collaborate. Thanks.

[tmelorc]

So, I'm trying to do a PR. I'm not sure if it will work. Please, when you can, check if it works.

[sauln]

Yes, it worked as is merged #34. Thank you!

I got error in line 15. What is wrong there ? Thanks

I am also getting same error, @FaisalAhmed77 did you get solution for this error?

[jaygam111]

When I run the Example Plots for Torus vs Sphere code, got an error.

AttributeError: module 'persim' has no attribute 'landscapes'

Any idea how to solve this?
