"not on PATH" warning building python packages

Help

Hi,
I got this warning

  WARNING: The script tensorboard is installed in '/nix/store/3nf1fxmrdfkx38jjskgq9x59lv2jjinr-python3.7-tensorboardx/bin' which is not on PATH.                                                                                                                          
  Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.

when building

tensorboard-plugin-wit = with pkgs.python37Packages; buildPythonPackage rec {
        name = "tensorboard-plugin-wit";
        version = "1.6.0.post3";
        format = "wheel";
        src = builtins.fetchurl {
          url = https://files.pythonhosted.org/packages/51/cd/a0c1f9e4582ea64dddf76c1b808b318d01e3b858a51c715bffab1016ecc7/tensorboard_plugin_wit-1.6.0.post3-py3-none-any.whl;
          sha256 = "0krxmwfrnl6l5qnpkyszpf9lh85h4yr8pvss419m8rpi8g1lmpqz";
        };
  };

tensorboardx = with pkgs.python37Packages; buildPythonPackage rec {
        name = "tensorboardx";
        version = "2.2.1";
        format = "wheel";
        src = builtins.fetchurl {
          url = https://files.pythonhosted.org/packages/1d/fd/4f3ca1516cbb3713259ef229abd9314bba0077ef6070285dde0dd1ed21b2/tensorboard-2.2.1-py3-none-any.whl;
          sha256 = "1hjd9drqs4dynikrgc3x4pilgpbiqxfmxjgkjfg6g1v1hp4jsals";
        };
        propagatedBuildInputs = [
          tensorboard-plugin-wit
          absl-py
          markdown
          numpy
          grpcio
          werkzeug
          google-auth-oauthlib
        ];
  };

in a nix-shell.

Am I missing something in some phases in buildPythonPackage?

No, during installation bin/ is simply not added to $PATH. No problem there. We may want to suppress that warning.

Thank you!

Now I wonder why I got error

ERROR: Could not find a version that satisfies the requirement tensorboardx (from simpletransformers==0.27.0) (from versions: none)
ERROR: No matching distribution found for tensorboardx (from simpletransformers==0.27.0)
builder for '/nix/store/n0krshq9nxa1chvx5qyaq33l0qpmcgi1-python3.7-simpletransformers.drv' failed with exit code 1

in building the following which needs tensorboardx

  simpleTransformers = with pkgs.python37Packages; buildPythonPackage rec {
        name = "simpletransformers";
        version = "0.27.0";

        src = fetchPypi {
          inherit version;
          pname = name;
          sha256 = "0y27gvv48wfywa1lxbd341z8ryb7r4mwn49g7v58vvswm51mdlm6";
        };

        propagatedBuildInputs = [
          tokenizers
          pandas
          seqeval
          regex
          scikitlearn
          tensorboardx
        ];

  };
