Hi,
I run the commond "python cdvae/run.py data=perov expname=perov", then the error rised "KeyError: 'PROJECT_ROOT not defined and no default value is present!'"

But my .env contant is "

export PROJECT_ROOT="/root/software/cdvae-main"
export HYDRA_JOBS="/root/software/cdvae-main/hydra"
export WABDB_DIR="/root/software/cdvae-main/wabdb"

"

Can you help me fix the error?
