Hello, I am new in smart contract world

Hi I am using following solidity version to test a new contact

pragma solidity ^ 0.6.2;

import "https://github.com/OpenZeppelin/openzeppelin-contracts/blob/v2.4.0/contracts/token/ERC20/ERC20.sol";

I am using remix and also using 0,6.2 +commit. bacdbe57 compiler but it is showing an error and saying that parser error: source files require different compiler version (current compiler is 0,6.2 +commit. bacdbe57.Emscripten.clang - note that nightly builds are considered to be strictly less than the released version pragma solidity ^0.5.0;
