ModuleNotFoundError: No module named 'plotly.validators.scatter3d.line'

[jeffbrownell]

I’m running into a ModuleNotFound error with plotly when running the below die_visual.py script. It imports plotly libraries and another small random script called die.py (below as well). These are short scripts so I took screenshots with line numbers to help. These are from the PytonCrashCourse book. The script works fine until I try to graph with plotly (lines 22-29 in die_visual.py).

Python Scripts:
#die.py

from random import randint

class Die:
    """A class representing a single die."""
    
    def __init__(self, num_sides=6):
        """Assume a six-sided die."""
        self.num_sides = num_sides
        
    def roll(self):
        """"Return a random value between 1 and number of sides."""
        return randint(1, self.num_sides)

#die_visual.py

from plotly.graph_objs import Bar, Layout
from plotly import offline

from die import Die

#Create a D6.
die = Die()

#Make some rolls, and store results in a list.
results = [  ]
for roll_num in range(1000):
    result = die.roll()
    results.append(result)
    
#Analyze the results.
frequencies = [  ]
for value in range(1, die.num_sides+1):
    frequency = results.count(value)
    frequencies.append(frequency)
    
#Visualize the results.
x_values = list(range(1, die.num_sides+1))
data = [Bar(x=x_values, y=frequencies)]

x_axis_config = {'title': 'Result'}
y_axis_config = {'title': 'Frequency of Result'}
my_layout = Layout(title='Results of rolling one D6 1000 times',
        xaxis=x_axis_config, yaxis=y_axis_config)
offline.plot({'data': data, 'layout': my_layout}, filename='d6.html')

Basic error output:
$ python3 die_visual.py
Traceback (most recent call last):
File "die_visual.py", line 29, in <module>
offline.plot({'data': data, 'layout': my_layout}, filename='d6.html')

Trouble-shooting efforts:
-Narrowing google searches stopping at ‘plotly.validators.scatter3d.line’
-I tried running the script from Idle and powershell directly in case there is something wonky with GitBash (MINGW64 on Windows10) but to no avail (same error in all three cases)
-Posted this same issue to the plotly.com forums. No responses yet.

Help?

I'm on 3.8.2/MacOS, but otherwise similar. It appeared to work for me (opened a web page with 6 bars on it and no error). You appear to be on windows. I've seen before bugs where something assumed a case insensitive filesystem, but I don't see any files that look like they would conflict in this manner.

You might want to try setting up a new venv, install only plotly and see if it happens in that venv as well.

[jeffbrownell]

Thanks for the suggestion. I moved the scripts to a venv, installed plotly==4.8.2 and the same error persists.
Uninstalled v4.8.2 and installed 4.7.0. Same error.
Tried v4.0.0 with the same error.
I'm at a loss with figuring this out.

[snippsat]

Tested code and it work Python 3.8.3 and Win-10.
The problem is that there is two Python version in that error message.
Example.

# Start
C:\Users\jebrow1\AppData\Roaming\Python\Python38\site-packages\plotly\offline\offline.py
# jump
File "E:\Python\Python38\lib\site-packages\_plotly_utils\basevalidators.py", line 2739, in validate_coerce
# jump back
File "C:\Users\jebrow1\AppData\Roaming\Python\Python38\site-packages\plotly\basedatatypes.py", line 3971, in __setitem__
self._set_compound_prop(prop, value)
.....ect

This is you main version

$ pip -V
pip 20.1.1 from e:\python\python38\lib\site-packages\pip (python 3.8)

# Same in <pip show plotly>
Location: e:\python\python38\lib\site-packages

So you have to get rid of this version.

C:\Users\jebrow1\AppData\Roaming\Python\Python38

Try uninstall,go into Roaming folder and make sure it gone(delete).
Check environment variables ,Restart and try again.
