I rarely use HTML and JavaScript and almost forget the most fundamentals. What is the error?
DevTools failed to load SourceMap: Could not load content for https://cdn.jsdelivr.net/npm/@tensorflow/tf.min.js.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

Go to the developer tools (F12 in the browser) then select the three dots in the upper right corner, and go to Settings. Then, look for Sources, and disable the options: “Enable javascript source maps” “Enable CSS source maps” If you do that, that would get rid of the warnings.
General source map error reporting js mentions a source map, and the source map URL tells us where to find the source map data (in this case, relative to the resource). The error tells us that the source map is not JSON data — so we're serving the wrong file.
This worked for me:
Go to Inspect → Settings (Symbol) gear → Uncheck Enable JavaScript source maps and Enable CSS source map.
Refresh.
(Note: Deactivate Adblock if the above process did not work.)

Newer files on JsDelivr get the sourcemap added automatically to the end of them. This is fine and doesn't throw any SourceMap-related notice in the console as long as you load the files from JsDelivr.
The problem occurs only when you copy and then load these files from your own server. In order to fix this for locally loaded files, simply remove the last line in the JavaScript file(s) downloaded from JsDelivr.
It should look something like this:
//# sourceMappingURL=/sm/64bec5fd901c75766b1ade899155ce5e1c28413a4707f0120043b96f4a3d8f80.map
As you can see, it's commented out, but Chrome still parses it.

This is what worked for me:
Instead of
<script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs"></script>
try
<script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs/dist/tf.min.js"> </script>
After that change I am not seeing the error any more.
