Hi! Sorry to bother you, sir. I need to ask you guys for help, I haven’t been able to connect to the MP library for the last 2 to 3 weeks. Accessing MP data from the sample code or from pymatgen will result in the following connection error. My mp_api version is 0.45.2 which should be the latest version, how can this be solved?
Hey @weitengzhang1227, can you check your network connection / VPNs?
Also ensure you have your API key properly set as an environment variable (MP_API_KEY) and that it is recognized in your jupyter environment:
import os
print(os.environ.get("MP_API_KEY"))
If the environment variable isn’t recognized, you can always manually input the API key into MPRester like:
with MPRester(api_key = < your API key > ) as mpr:
# do client operations hereHi！I’m sorry I haven’t been able to see a reply after being busy.,I’ve already filled in the key in this part.。 After I followed your instructions, I filled in the new version of the key correctly in the API key code. However, it’s a shame that the results are still as I reported earlier.
We haven’t had reports of widespread outages, so it’s probably a local network issue. Can you try:
- Using a VPN to get around internet service provider / governmental firewalls
- Ensuring that any firewalls you use on your computer permit traffic to MP by accessing the API documentation or using the materials explorer app
- Using a different network connection (e.g., ethernet, wifi at a cafe/work/school)?
