-XX:SoftRefLRUPolicyMSPerMB=50
-ea
-Dsun.io.useCanonCaches=false
-Djava.net.preferIPv4Stack=true
-Djdk.http.auth.tunneling.disabledSchemes=""
-XX:+HeapDumpOnOutOfMemoryError
-XX:-OmitStackTraceInFastThrow

Steps 3 –

Change the value for -Xmx750m  by -Xmx1024m or -Xmx2048m or as per your requirement. Now you may restart the Pycharm. That’s all.

Another way –

You may do it internally from IDE Pycharm itself. All you need to Go Help ->Find Action ->Edit Custom VM option. It will open the same file as you see in step 3 above. Change the values here and restart the Pycharm.
