New to Plotly / Python and Need some Help

Hello,

I have just started Python a few weeks ago and Plotly today. I ultimately am looking to plot a US county map, but in the getting started phase, I am having issues plotting basic plots. I am using Jupyter Notebook from Anaconda.

I am doing the following code with the then resulting error. I assume it is a basically minor error that I cannot figure out.

import plotly
plotly.tools.set_credentials_file(username=‘jtanguay’, api_key=‘keyinhere’)

import plotly.plotly as py
import plotly.graph_objs as go

trace0 = go.Scatter(
x=[1, 2, 3, 4],
y=[10, 15, 13, 17]
)
trace1 = go.Scatter(
x=[1, 2, 3, 4],
y=[16, 5, 11, 9]
)
data = [trace0, trace1]

py.plot(data, filename = ‘basic-line’, auto_open=True)

Hi Justin,

I just ran your code in my own Jupyter notebook, and the code itself runs fine. I suspect something is wrong with your api_key. Did you sign up for one when setting up your Plotly account? If so, maybe you have reached your max 25 charts for the month? I know Plotly has a limit on how many charts you can load to your account - if that’s the case, just delete some charts that you no longer need/are older versions. Let me know if that helps.

Hi Jess,

I just signed up yesterday for Plotly, and that was my second graph I tried. I checked my credentials and I copy and pasted from there.

Could it be something that is blocking me from properly loading such as my Anaconda edition or version of plotly I installed via pip?

No matter what I try in Anaconda, I have to install via pip and not the conda install method.

Thanks,

Justin

Hello Justin,
welcome to the Python fold. :man_technologist::metal:

I minor remark. For reasons beyond my limited intelligence, Anaconda install an Anaconda Prompt which is set up with paths to your Python installation and repositories for your installed python packages.
If you open a normal commando prompt and pip install something, I am unsure if it installs in a repository which is recognized by Anaconda.
If you, on the other hand, pip install python packages using your Anaconda Prompt, I am close-to-but-not-100pct sure that it will install to The Good Repository™ where your Anaconda-Python is looking for packages. :slightly_smiling_face:

Hi Blaceus,

Thank you for the help and the warm welcome. I went back in the process and reinstalled Anaconda and made sure I installed Plotly properly. I am still getting one of two error messages.

If I try py.sign_in : PlotlyError: Sign in failed. I have verified that my api key is correct.

If I just use py.tools.set_credentials_file I get the following error: PlotlyRequestError(message, status_code, content)

PlotlyRequestError: No message

Is there a way to ensure I installed “The Good Repository”? Or is there another way to fix this basic issue?

Thanks again for helping a Newbie

Justin

Frankly, I am unable to help you with plotly sign-in problems. I have no experience with this.
An easy way to check if your packages are installed in the Anaconda folder go to the following repository on your computer:
“C:\Users<your user name here>\AppData\Local\Continuum\anaconda3\Lib\site-packages”
And see if you can locate folders with the names of the packages you have installed. :slightly_smiling_face:
