为什么plotly express做折线图时会提示属性错误？

Question

I am trying to use plotly to build a line chart. Here is the code I wrote:

from fredapi import Fred
import plotly.express as px
fred = Fred("1c242ee90989c94ffb93c923d94e855f")
tran = pd.DataFrame(fred.get_series("EMISSCO2TOTVTCTOUSA"))
tran.columns = ["CO2"]
tran = tran.reset_index()
fig = px.line(tran, x = "index", y = "CO2")
fig.show()

Why do I get the following error:

AttributeError: 'object' object has no attribute 'layout'

Answer 1

Using the latest version of Plotly (version 5.4.0 at the time of posting), I can produce a line chart from your code.

from fredapi import Fred
import plotly.express as px
fred = Fred("1c242ee90989c94ffb93c923d94e855f")
tran = pd.DataFrame(fred.get_series("EMISSCO2TOTVTCTOUSA"))
tran.columns = ["CO2"]
tran = tran.reset_index()
fig = px.line(tran, x = "index", y = "CO2")
fig.show()
