Installing Minerl on remote cluster #48

Closed russelltankl closed 4 years ago

russelltankl commented 5 years ago

After several days of waiting for the cluster admin to install correct java versions, I got this error when I do pip install --upgrade minerl on the cluster. My local machine seems to install perfectly fine.

@DazaiSan would you please upgrade your package and see if this issue still occurs (Make sure to install from pip not from this repository/source).

pip3 install --upgrade minerl
aminakmim commented 5 years ago

It's working !!!! Thank you so much ^_^

russelltankl commented 5 years ago

@MadcowD I could install minerl successfully this time around! However, running the hello world example, the gym.make command, gave me this error.

@russelltankl Does your machine have an internet connection?

MadcowD commented 5 years ago

@russelltankl IT could also be that your java CA certificates are at fault.

(See https://stackoverflow.com/questions/29584328/gradlew-bat-and-gradlew-sslhandshakeexception)

sudo dpkg --purge --force-depends ca-certificates-java
sudo apt-get install ca-certificates-java
russelltankl commented 5 years ago

@MadcowD Yes it does have internet connection, it's a headless machine accessed via ssh. I'll try to see what I can do to with the java CA certificates solution you proposed.
