To reproduce:
(haystack) C:\Users\Haystack\NewStart>python squad_to_dpr.py --squad_input_filename answers.json --dpr_output_filename C:\Users\Haystack\NewStart\dpr.json

The output
Using SQuAD-like file answers.json
The system cannot find the path specified.
Traceback (most recent call last):

	def __prepare_ElasticsearchDocumentStore():
	es = Elasticsearch(["http://localhost:9200/"], verify_certs=True)
	if not es.ping():
	logger.info("Starting Elasticsearch ...")
	status = subprocess.run(
	['docker run -d -p 9200:9200 -e "discovery.type=single-node" elasticsearch:7.9.2'], shell=True
	)
	if status.returncode:
	raise Exception("Failed to launch Elasticsearch.")

The script checks if Elasticsearch is running on localhost:9200
If not, it attempts to start Elasticsearch using Docker.

In your case, it probably fails because you don't have Docker.

You can avoid this error if you install and start Elasticsearch yourself.
To understand how to do this on Windows, see this guide.

@anakin87 Is that mean i cannot run in google colab or anaconda prompt?
