Following "Forecast using TimeGPT in 3 easy steps", I have got the key, but when I run code, it fails.

In addition, when I run nixtla_client.validate_api_key(), it shows False. But I'm sure I just get the key from dashboard.nixtla.io (the key is active as shown on the webpage).

Versions / Dependencies

python: 3.11
OS: windows 10
nixtla: 0.6.1

Reproducible example

import pandas as pd
from nixtla import NixtlaClient

1. Instantiate the NixtlaClient

nixtla_client = NixtlaClient(api_key = 'xxxx')

2. Read historic electricity demand data

df = pd.read_csv('https://raw.githubusercontent.com/Nixtla/transfer-learning-time-series/main/datasets/electricity-short.csv')

3. Forecast the next 24 hours

fcst_df = nixtla_client.forecast(df, h=24, level=[80, 90])

4. Plot your results (optional)

nixtla_client.plot(df, fcst_df, level=[80, 90])

Issue Severity

None

Hey @jmren168. Are you able to run this code in google colab or some other environment? This is most likely related to your firewall.
