Find job in Vancouver

I have been in Canada for three weeks and I am looking for a job. I have applied to various companies and positions, even general ones, but I have not received any response. I am very stressed now and I don't know what to do.

I have two years of experience as a Python programmer and I am specialized in machine learning and deep learning. I would appreciate it if you could guide me on what to do.

I am a newcomer and I do not know anyone who can give me a referral, so I do not know what to do.
