Final complete

There is only one empty cell left in row 7 so we can enter the 1 there. Entering the 1 in row 7 eliminates all other possibilities for the 1 in block 2 so we can enter a 1 in the lower left-hand cell.

Entering the 1 in row 3 eliminates one of the possibilities for the 7 in that block so we can enter the 7 and that in turn eliminates one of the two 7s in block 8 and allows us to enter the 7 there.

Checking column 4, we need to place the 4 and 9. There's already a 4 in row 2 so the 4 must go in row 5 and the 9 in row 2.

In row 5 we are missing the 3 and 9. The 3 has to go in block 4 (there is already a 9 there) and the 9 in block 5. This leaves one empty cell in each of these blocks. So enter the 3 and the 4 in their respective cells

>Now go to row 2. We can place the 2 and 6 in the last two cells in this row (the 6 has to go in block 2). Since we have 2 in the first cell of row 2, that determines where the 1 and 2 go in row 9.

After placing the 1 and 2 in row 9, we can complete row 3 by entering the 9 and the 4.

Now we have three columns with only one empty cell. After entering those numbers we have only to complete column five and the puzzle is solved!
