An unexpected error has occurred. Conda has prepared the above report.
Upload did not complete.Cause Analysis:
This reason is caused by abnormal network connection. The key to solving the problem is:
1. Is the network connection abnormal?
2. Whether you are using circumvention software and starting the system agent?
solution:
1. Check whether circumvention software is used and the proxy settings are turned on. If yes, the environment can be created after closing the agent
2. Start anaconda prompt here to create the environment
As shown above, the environment is created successfully!
At this point, the problem is solved.
