expansion of convert & no convert on gpu019

vs on gpu019

ERROR: IOError: could not spawn `convert cv-cubic-1.png fit-cubic-1.png loss-cubic-1.png +append cubic-1.png`: no such file or directory (ENOENT)

the second one should be due to no such command on gpu019, but it exists on sandbox

@chpc-sandbox ~]$ which convert
/usr/bin/convert

@chpc-gpu019:/usr/bin$ ls | grep convert
btrfs-convert
dpatch-convert-diffgz
mariadb-service-convert
mysql_convert_table_format

[szcf-weiya]

a workaround is

julia> run(`ssh sandbox convert cv-cubic-1.png fit-cubic-1.png loss-cubic-1.png +append cubic-1.png`)
