Hi there,

After finishing my fraction_rows_missing function and running the test function fraction_rows_missing_test(fraction_rows_missing, X_train, X_val, X_test), I get:

Example dataframe:

     a    b
0  NaN  1.0
1  1.0  NaN
2  1.0  0.0
3  NaN  1.0 

Computed fraction missing:  0.75
Fraction of rows missing from X_train:  0.6986594132504371
Fraction of rows missing from X_val:  0.703962703962704
Fraction of rows missing from X_test:  0.0
Error: Wrong shape.
2  Tests passed
1  Tests failed

AssertionError: Not all tests were passed for fraction_rows_missing. Check your equations and avoid using global variables inside the function.

The outputs are all correct but I get wrong shape. However, the output is a fraction so not sure what the problem is.

My function is

sorry, forgot is not allowed to post code.

My ID is tmfnvtfx

Any ideas what is the problem?
