Troubleshooting

Getting Help

If you experience problems using the Data Marketplace, you can seek additional help through the following channels:

  • Join our Catalyst Forum, and browse a variety of topics and conversations around common issues that others face when using Catalyst and the Data Marketplace, and how to resolve them. And join the conversation!
  • Join our Discord community, and head over the #marketplace channel where many other users (as well as the project developers) hang out, and can assist you with your particular issue. The more descriptive and the more information you can provide, the easiest will be for others to help you out.
  • Report the problem you are experiencing on our GitHub repository following the guidelines provided therein. Before you do so, take a moment to browse through all previous reported issues in the likely case that someone else experienced that same issue before, and you get a hint on how to solve it.

Known Issues

If you get errors like either one of these:

File "(...)/virtualenv/lib/python3.6/site-packages/eth_keyfile/keyfile.py", line 7, in <module>
  from Crypto.Protocol.KDF import scrypt
ImportError: cannot import name 'scrypt'
File "(...)/virtualenv/lib/python3.6/site-packages/eth_keyfile/keyfile.py", line 5, in <module>
  from Crypto import Random
ImportError: cannot import name 'Random'

Make sure you don’t have package PyCrypto installed, which is not being maintained currently:

pip uninstall pycrypto

and it that was the case, reinstall package pycryptodome:

pip uninstall pycryptodome; pip install pycryptodome
