C1 W3: I keep facing this error quite often can someone help me out

Hello Tejesh,

Kindly look into the codes related dZ1 as per the instructions given before the grader Code cell based on the below image

Also from next time, please select the week also when you posting a query and if possible mention the assignment name. It helps more when the learner also puts effort in looking their issue as it will help mentors to quickly look at where the issue is focused on like the Unique cell number or exercise cell or like in the previous post when you posted you mentioned the cell name.

your position of cache is incorrect with the dZ1

Regards
DP

Thank you i fixed the error. I shall keep in mind to mention the exercise number and assignment name
