conda install -c fvcore -c iopath -c conda-forge fvcore iopath

When encountering an error

An unexpected error has occurred. Conda has prepared the above report.

If submitted, this report will be used by core maintainers to improve
future releases of conda.
Would you like conda to send this report to the core maintainers? [y/N]: 
Timeout reached. No report sent.

I am not sure what caused this, but I successfully installed the environment on my other computer and ran the code. I have been experiencing the above error in my new computer configuration, which has been bothering me for many days.
