exec pip install -r requirements.txt error

Invalid requirement: 'version https://git-lfs.github.com/spec/v1'
It looks like a path. Does it exist ?

I find https://git-lfs.github.com/spec/v1 does not exist.
The Jupyter code helped me ceate table weather_data in PostgreSQL weather db, but didn't ingest data in 2015.csv.

In the "Ingest_Data_Into_PostgreSQL.ipynb" jupyter notebook, the last command (26) does not work and gives a python error.

Command:

Finally, we want to label the 5 types of weather data noted above with human-readable names. We create a dictionary mapping each label to its description, create a Data Frame from that, and write it to the database

weather_type_dict = {'PRCP': 'Precipitation', 'SNOW': 'Snowfall', 'SNWD': 'Snow Depth', 
                     'TMAX': 'Maximum temperature', 'TMIN': 'Minimum temperature'}
weather_type_df = DataFrame(weather_type_dict.items(), columns=['weather_type', 'weather_description'])
description_table_name = 'weather_types'
weather_type_df.to_sql(description_table_name, conn, index_label='id')

Error when executed:

...
----> 3 weather_type_df = DataFrame(weather_type_dict.items(), columns=['weather_type', 'weather_description'])
...
PandasError: DataFrame constructor not properly called!

I got this:

does it have other download link?

Hi,

I am strugglling to ingest the weather data into database. When I run the command#6 starting with
db_name = 'weather'
I get the value error as mentioned in the title.

I double checked my database for the table and there is no relation presetnt at all , forget one with that name.

weather=# \dt
Did not find any relations.

I gave table a new name as well with hope that I may be able to create a table with new name but no success there either.

I noticed the author's comment that trying to write large data at a time can cause notebook to crash thus I tried reducing the chunk size too but still no success.

Any advice will be gracefully received.

Thanks
